CVSS v3.1 |
| A flaw was found in Pulp, as used in Red Hat CloudForms. This vulnerability allows a local user to read the administrative password due to world-readable permissions on the `pulp.conf` configuration file. This information disclosure could enable unauthorized access to sensitive system credentials. |
| A flaw was found in the OpenShift Cloud Credential Operator Mint-mode IAM policies for AWS. Operator credentials are provisioned with account-wide scope for destructive actions rather than being restricted to cluster-owned resources, enabling cross-scope impact after credential compromise. |
| The Redis server command parser in Apache bRPC accepts an empty RESP array as a command header. A remote unauthenticated attacker who can reach a bRPC server with Redis service enabled can send an empty array header followed by a bulk string, causing an out-of-bounds write in the parser and crashing the process.
Root Cause:
RedisCommandParser::ConsumeImpl rejected negative RESP array counts but accepted zero. It resized the command argument vector to zero elements and continued parsing. When a following bulk string was parsed, the only index guard was a CHECK. In configurations where fatal logs do not abort immediately, execution could continue and write to _args[0] even though the vector was empty.
Affected Scenarios:
Deployments that enable ServerOptions.redis_service and accept Redis protocol traffic from untrusted clients. The issue is reached during parsing before command handling or authentication.
How to Fix:
1. Upgrade bRPC to version 1.18.0, which fixes this issue.
2. Apply this patch: https://github.com/apache/brpc/pull/3354
Note:
The fix rejects empty RESP arrays as invalid Redis commands and replaces the internal index CHECK with an explicit parse error so malformed command streams cannot fall through to an indexed vector write. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/pci: Fix leak of uninitialized kernel data in SCLP report
While report_error_write() checks that the provided buffer is at least
as large as the header struct, but not that it is large enough to
contain the report with the length claimed by report->length. If
user-space provides a short buffer, meaning a larger report->length than
the actually written payload, up to around 4K of kernel data from past
the kmalloc(len + 1) sized buffer allocated in kernfs_fop_write_iter()
will leak into the SCLP report.
However, as the entity processing the SCLP is privileged and able to
access at least the page including the report, this does not leak data
that entity could not access but it is still an out of bounds read and
a malformed error report that should be rejected. |
| In the Linux kernel, the following vulnerability has been resolved:
rtc: mpfs: fix unchecked devm_clk_get() error pointer in probe()
devm_clk_get(&pdev->dev, "rtcref")'s return value was passed straight
into clk_get_rate() without checking it for an error first, unlike the
"rtc" clock a few lines above which is correctly checked with
IS_ERR(). clk_get_rate() only guards against a NULL clk, not an error
pointer:
if (!clk)
return 0;
...
rate = clk_core_get_rate_recalc(clk->core);
so if devm_clk_get() ever returns an error pointer here (for example
ERR_PTR(-EPROBE_DEFER), which is the normal, expected outcome if the
clkcfg clock-provider this RTC depends on has not registered its
clocks yet by the time this driver probes), clk_get_rate() dereferences
that error pointer instead of returning 0, crashing instead of letting
probe defer.
Capture the clock in the existing 'clk' local and check it with
IS_ERR() before calling clk_get_rate(), matching the handling already
used for the "rtc" clock in this same function. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: spi-qcom-qspi: Fix incomplete error handling in runtime PM
The runtime PM functions had incomplete error handling that could leave the
system in an inconsistent state. If any operation failed midway through
suspend or resume, some resources would be left in the wrong state while
others were already changed, leading to potential clock/power imbalances.
Reorder the suspend/resume sequences to avoid brownout risk by ensuring the
performance state is set appropriately before clocks are enabled and clocks
are disabled before dropping the performance state.
Fix by adding proper error checking for all operations and using goto-based
cleanup to ensure all successfully acquired resources are properly released
on any error. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: check if root is readonly when setting posix acl
For a filesystem which has btrfs read-only property set to true, all
write operations including acl and xattr should be denied. However, acl
can still be set even if btrfs ro property is true.
This happens because no function on the set_acl code path checks the root
is readonly or not. It was checked in btrfs_setxattr_trans() but got
removed in commit 353c2ea735e4 ("btrfs: remove redundant readonly root
check in btrfs_setxattr_trans")
That commit didn't check if all the callers properly check the root's
read-only flag. A previous fix is commit b51111271b03 ("btrfs: check if
root is readonly while setting security xattr").
Always check if the root is read-only before performing the set acl
operation. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: zero pipe read compound padding
Compound response handling extends the last response iov to an eight-byte
boundary.
smb2_read_pipe() allocates only the payload size, so the alignment padding
can expose up to seven bytes of uninitialized kernel heap memory.
Allocate the aligned size and clear the unused tail before pinning the
response buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
nfsd4_create() stores the return value of nfsd4_acl_to_attr() in
status, but the switch(create->cr_type) block unconditionally
overwrites it in every branch. ACL translation errors are silently
discarded, and the CREATE proceeds without the requested ACL.
Add an early exit check after nfsd4_acl_to_attr(), matching the
pattern already used in nfsd4_setattr().

| In the Linux kernel, the following vulnerability has been resolved:
vhost: fix vhost_get_avail_idx for a non empty ring
vhost_get_avail_idx is supposed to report whether it has updated
vq->avail_idx. Instead, it returns whether all entries have been
consumed, which is usually the same. But not always - in
drivers/vhost/net.c and when mergeable buffers have been enabled, the
driver checks whether the combined entries are big enough to store an
incoming packet. If not, the driver re-enables notifications with
available entries still in the ring. The incorrect return value from
vhost_get_avail_idx propagates through vhost_enable_notify and causes
the host to livelock if the guest is not making progress, as vhost will
immediately disable notifications and retry using the available entries.
This goes back to commit d3bb267bbdcb ("vhost: cache avail index in
vhost_enable_notify()") which changed vhost_enable_notify() to compare
the freshly read avail index against vq->last_avail_idx instead of the
previously cached vq->avail_idx. Commit 7ad472397667 ("vhost: move
smp_rmb() into vhost_get_avail_idx()") then carried over the same
comparison when refactoring vhost_enable_notify() to call the unified
vhost_get_avail_idx().
The obvious fix is to make vhost_get_avail_idx do what the comment
says it does and report whether new entries have been added. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix kernel BUG in ext4_write_inline_data_end
When the data=journal mount option is used, the ext4_journalled_write_end()
function incorrectly calls ext4_write_inline_data_end() without checking
if the EXT4_STATE_MAY_INLINE_DATA flag is still set on the inode.
If a previous attempt to convert the inline data to an extent failed (e.g.
due to ENOSPC), the EXT4_STATE_MAY_INLINE_DATA flag is cleared, but
the EXT4_INODE_INLINE_DATA flag remains set. In this scenario, the next
call to ext4_write_begin() will not prepare the inline data xattr for
writing, but ext4_journalled_write_end() will incorrectly attempt to write
to it, triggering a BUG_ON(pos + len > EXT4_I(inode)->i_inline_size) in
ext4_write_inline_data() since i_inline_size was not expanded.
Fix this by ensuring that ext4_journalled_write_end() only calls
ext4_write_inline_data_end() if the EXT4_STATE_MAY_INLINE_DATA flag is
set, mirroring the behavior of ext4_write_end() and ext4_da_write_end(). |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: use opener credentials for ADS I/O
Alternate data streams are stored as xattrs. Unlike regular file I/O,
their read and write paths therefore call VFS xattr helpers which recheck
inode permissions and LSM policy using the current task credentials.
Run ADS I/O with the credentials captured when the SMB handle was opened. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phonet: do not BUG_ON() in pn_socket_autobind() on failed bind
syzbot reported a kernel BUG triggered from pn_socket_sendmsg() via
pn_socket_autobind():
kernel BUG at net/phonet/socket.c:213!
RIP: 0010:pn_socket_autobind net/phonet/socket.c:213 [inline]
RIP: 0010:pn_socket_sendmsg+0x240/0x250 net/phonet/socket.c:421
Call Trace:
sock_sendmsg_nosec+0x112/0x150 net/socket.c:797
__sock_sendmsg net/socket.c:812 [inline]
__sys_sendto+0x402/0x590 net/socket.c:2280
...
pn_socket_autobind() calls pn_socket_bind() with port 0 and, on
-EINVAL, assumes the socket was already bound and asserts that the
port is non-zero:
err = pn_socket_bind(sock, ..., sizeof(struct sockaddr_pn));
if (err != -EINVAL)
return err;
BUG_ON(!pn_port(pn_sk(sock->sk)->sobject));
return 0; /* socket was already bound */
However pn_socket_bind() also returns -EINVAL when sk->sk_state is not
TCP_CLOSE, even when the socket has never been bound and pn_port() is
still 0. In that case the BUG_ON() fires and panics the kernel from a
user-triggerable path.
Treat the "bind returned -EINVAL but pn_port() is still 0" case as a
regular error and propagate -EINVAL to the caller instead of crashing.
Existing callers already translate a non-zero return from
pn_socket_autobind() into -ENOBUFS/-EAGAIN, so returning -EINVAL here
only changes behaviour from panic to a normal errno. |

drm/amd/display: Validate function returns
[WHAT & HOW]
Function return values must be checked before data can be used
in subsequent functions.
This fixes 4 CHECKED_RETURN issues reported by Coverity. |
| The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`)
that scans container processes for runtime fingerprinting. When scanning a
container, the coordinator:
1. **fork()s** a child process
2. **setns()** into the target container's PID and mount namespaces
3. **fchdir()** back to an orphaned FD pointing at the extractor's own root
filesystem (where `/crio.sock` is hostPath-mounted)
4. Calls **only `seteuid(target_uid)`** — changing the effective UID but leaving
the **real UID and saved-set-UID at 0** and **retaining the permitted
capability set**
5. The `check_no_privileged_perms()` guard inspects only the Effective capability
set (so it passes), and is **skipped entirely when the target runs as uid 0**
6. The `VersionExecutable` fingerprint invokes `fpr_kind_executable` with
`process.command_line[0]` — the target's argv[0], read from
`/proc/<pid>/cmdline` and **fully controlled by the workload**
7. `fpr_kind_executable` calls `exec.Command(executable, "--version").Output()`
— executing the **workload's own binary** inside the workload's mount
namespace while **ruid=0 in the host user namespace**
The executed process can call `setuid(0)` to restore full root with
`CAP_SYS_ADMIN`, and inherits the orphaned cwd which resolves into the extractor
container's filesystem containing the host CRI-O socket.
## Affected Code
### 1. Insufficient privilege drop (Rust — extractor coordinator)
**File:** `extractor/src/insights_runtime_extractor.rs`
```rust
// Lines 139-146 — seteuid-only drop, guard skipped for root containers
join_process_namespaces(process.pid)?;
change_dir(current_dir);
switch_user(*process.uid)?;
if *process.uid != 0 {
perms::check_no_privileged_perms()
.expect("Must not have privileged permissions to run fingerprints");
}
fingerprint::run_fingerprints(&config, out_dir, &process);
```
```rust
// Lines 182-185 — only effective UID changed; ruid/suid stay 0
fn switch_user(uid: u32) -> Result<(), ScannerError> {
debug!("... Becoming user: {uid}");
seteuid(uid.into()).map_err(|e| ScannerError::Errno(e))
}
```
### 2. Execution of untrusted binary (Go — fingerprint)
**File:** `fingerprints/pkg/utils/file.go`
```go
// Lines 75-80 — executes a path taken verbatim from workload's argv[0]
func GetExecutableVersionOutput(executable string) (string, error) {
out, err := exec.Command(executable, "--version").Output()
if err != nil {
return "", err
}
return string(out), nil
}
```
### 3. Workload-controlled path forwarded (Rust — version_executable)
**File:** `version_executable.rs`
```rust
// Lines 29-34 — workload-controlled command_line[0] forwarded to fingerprint
return Some(vec![
fpr_kind_executable,
out_dir.to_string(),
String::from(&process.command_line[0]),
String::from(&version_executable.runtime_kind_name),
]);
```
## Attack Pattern
**Attacker:** Any tenant able to schedule a pod (unprivileged, any namespace)
**Victim:** The node running the insights-runtime-extractor DaemonSet
**Trigger:** Automatic — the DaemonSet scans all container processes on the node
**Attack sequence:**
1. Attacker creates a pod whose process name matches a configured
versioned-executable pattern (`node`, `python`, `python3`, `MainThread`,
or contains `java`)
2. The pod's main binary (at the path matching argv[0]) is a malicious
executable that calls `setuid(0)` to restore root
3. When the insights operator triggers a scan, the DaemonSet forks, enters the
attacker's mount namespace, and executes the attacker's binary with ruid=0
4. The attacker's code regains full root with `CAP_SYS_ADMIN` in the host user
namespace
5. The inherited cwd contains the host CRI-O socket → full node compromise |
| ServiceNow has remediated an information disclosure vulnerability that was identified in the ServiceNow AI Platform. This vulnerability could cause a user's plaintext password to be persisted in a system table, potentially exposing that password to a user who otherwise would not be entitled to view it.
ServiceNow remediated the vulnerability through security updates that address the unintended persistence of plaintext credentials. We are not currently aware of malicious exploitation against ServiceNow instances. We recommend customers promptly apply appropriate updates or upgrade to a patched release if they have not already done so. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/rocket: clear rdev on device init failure
rocket_probe() stores the return value from rocket_device_init() in the
file-scoped rdev pointer before checking whether it is an error pointer.
If rocket_device_init() fails, rdev is left as an ERR_PTR.
The rdev pointer is also used as the marker for whether the shared rocket
device has already been initialized. A later core probe can therefore see
a non-NULL rdev, skip rocket_device_init(), and dereference the error
pointer when reading rdev->num_cores.
Save the error code and clear rdev before returning from the
rocket_device_init() failure path. |
| In the CGM CLININET application server, multiple processes responsible for HL7 communication with external systems run with root privileges while processing untrusted data received from those external systems. An attacker in adjacent network able to send data to these HL7 communication processes can achieve remote code execution with root privileges.
The vulnerability was confirmed to affect versions up to 2026.MS3 but later versions may also be vulnerable. |
