| FrodoBots EarthRover Mini+ firmware (version 6.2.4_6.2.5_0.614.0) contains an insecure STM32 firmware update mechanism. The STM32 motor‑controller firmware is fetched over unencrypted HTTP. Integrity is validated only via MD5, with the hash provided in the same unprotected response. No code‑signing mechanism is implemented, allowing firmware to be replaced with potentially malicious code. |
| An arbitrary file write vulnerability exists in the underlying operating system of HPE Networking Fabric Composer. Successful exploitation could allow an authenticated local attacker to create or overwrite arbitrary files on the affected system with elevated privileges. |
| Improper Access Control in the program installation folder in NEC Corporation WebSAM Winshare Ver 7.5.0 and earlier (excluding Ver 7.3.3), Ver 7.6.0 and Ver 7.7.0 through 7.7.1 on Windows allows a locally authenticated low-privileged attacker to execute arbitrary code with SYSTEM privileges via a crafted DLL file that is loaded by a SYSTEM-level process. |

| In the Linux kernel, the following vulnerability has been resolved:
tun: Require CAP_NET_ADMIN to attach to an ownerless device
Twenty years ago I made creating a tuntap device require CAP_NET_ADMIN
in commit ca6bb5d7ab22 ("[NET]: Require CAP_NET_ADMIN to create tuntap
devices.")
The idea was to allow the permissions on /dev/net/tun to be relaxed to
0666 and thus allow owners of tun devices assigned with TUNSETOWNER to
actually open it and get at their devices.
What we missed at the time was that persistent devices with *no* owner
were already essentially world-consumable, and anyone who could open
the device node could also attach to those.
Even then, using persistent devices with no explicitly set owner — on
the (false) presumption that CAP_NET_ADMIN would be required to open
them — wasn't an egregious userspace bug. There are cases where it does
make sense to separate the creation/configuration of the netdevice, from
the process which shovels packets into it.
Since then, TUNSETGROUP was added a year later in commit 8c644623fe7e
("[NET]: Allow group ownership of TUN/TAP devices."). Its commit message
noted that if both uid and gid are set, both have to match (in itself a
bizarre choice) — but still not that with *neither* set, no permission
at all was required.
Then in 2012 commit c8d68e6be1c3 ("tuntap: multiqueue support") allowed
new queues to be attached to a device from the moment of its creation,
with no way for userspace to close the race between creation and a
subsequent TUNSET{OWNER,GROUP}.
In 2024, commit 3ca459eaba1bf ("tun: fix group permission check") tried
to fix things to be saner: only require the user *or* the group to
match, in line with standard POSIX permissions, and require
CAP_NET_ADMIN if neither the user nor group authorised the access
(although it put the CAP_NET_ADMIN check first, and would wrongly have
reported the capability as having been used even when it was not).
That fix was reverted in commit a70c7b3cbc06 ("tun: revert fix group
permission check") due to allegedly causing a regression in an selinux
test suite which *expected* the attachment to succeed when authorised
by none of user, group, nor CAP_NET_ADMIN:
https://lore.kernel.org/netdev/CAFqZXNtkCBT4f+PwyVRmQGoT3p1eVa01fCG_aNtpt6dakXncUg@mail.gmail.com/
We should not break UAPI. But we don't have to consider an selinux test
case which deliberately exercises a security flaw to be UAPI worth
preserving either. To which end, I have fixed it in selinux-testsuite
commit b2f894f0016b ("tests/tun_tap: set an owner on the device for the
relabel tests").
So: fix the lack of CAP_NET_ADMIN check on devices which *haven't* been
assigned an owner or group, while leaving the weird tun ownership model
as it was (user *and* group have to match, if both are set). If someone
still wants to fix the latter (which wasn't actually the reason the
previous attempt was reverted), they can do it under separate cover.
Permit attaching to an existing device only if an owner and/or group was
set and the caller matches all that were set, or if the caller has
CAP_NET_ADMIN. The only behavioural change is that a device with no
owner or group now requires CAP_NET_ADMIN to attach — precisely the
loophole we want to close.
And put the CAP_NET_ADMIN check in the right place this time. |
| Vikunja before 2.7.1 contains an insecure file permissions vulnerability that allows local users to read stored data because localStorage.Write creates blobs world-readable. Local attackers on a shared host can read attachments, project backgrounds and exports, and copy the SQLite database to crack password hashes offline. |
| Vikunja before 2.7.1 contains an insecure file permissions vulnerability that allows local users to read dump archives created with umask permissions by the vikunja dump command. Local attackers on a shared host can read the world-readable zip in the rootpath to obtain config, password hashes, TOTP secrets, tokens, and stored files. |
| A vulnerability was found in ESEngine DeepSeek-Reasonix up to 1.33.0. Impacted is the function loadGitStatus of the file build.rs of the component Build Script Execution. Performing a manipulation results in permission issues. The attack may be initiated remotely. Upgrading to version 1.34.0 is recommended to address this issue. The patch is named a54659c2c5b0f4e57aae2b44d41f421c6a71e8cf. You should upgrade the affected component. |
| A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba's permissions. |
| Vulnerability in the Oracle Product Lifecycle Analytics product of Oracle Supply Chain (component: Installation Issues). The supported version that is affected is 3.6.1. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Product Lifecycle Analytics executes to compromise Oracle Product Lifecycle Analytics. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Product Lifecycle Analytics accessible data. CVSS 3.1 Base Score 5.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N). |
| Local privilege escalation in `SmartUpdate.exe` and `SmartExecute.exe` in INFINITT Healthcare Co., Ltd. INFINITT PACS allows a local low-privileged attacker to execute arbitrary commands with administrator privileges via modification of a world-writable `execlist.txt` command manifest that is processed during application updates. |
| IRISPowerscan contain an insecure default
configuration where the built-in installation account is assigned elevated
privileges with a predictable password, which could allow an unauthenticated
attacker to gain unauthorised access to privileged application functionality. |
| In HPE Cray Programming Environment versions 25.03 and 25.09, prior to 26.03, the method that CPE is deployed on HPCM potentially allows elevated access by a local unprivileged user. |
| In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: add missing netlink_ns_capable() check for peer netns
rtnl_newlink() lacks a CAP_NET_ADMIN capability check on the peer
network namespace when creating paired devices (veth, vxcan,
netkit). This allows an unprivileged user with a user namespace
to create interfaces in arbitrary network namespaces, including
init_net.
Add a netlink_ns_capable() check for CAP_NET_ADMIN in the peer
namespace before allowing device creation to proceed. |
| Incorrect permissions on the Checkmk Windows agent's data directory, caused by a race condition that discards the permission changes during service start, in Checkmk <2.5.0p18, <2.4.0p39, <2.3.0p52 and 2.2.0 (EOL) allow a local user to execute arbitrary code as SYSTEM by placing scripts in the agent's plugins or local folders, and to read the agent controller's private key. |
| A weakness has been identified in kubescape up to 4.0.15. Impacted is the function GetWriter of the file core/pkg/resultshandling/printer/printresults.go of the component Output. Executing a manipulation of the argument outputFile can lead to permission issues. The attack requires local access. Upgrading to version 4.0.16 is recommended to address this issue. This patch is called d90f77314c7d4f2b53cf2425844bde2315bd26d2. Upgrading the affected component is advised. |
| filelock is a platform-independent file lock for Python. From version 3.30.0 until version 4.2.1, StrictSoftFileLock and AsyncStrictSoftFileLock on POSIX systems create coordination and claim directories without applying the caller’s restrictive lock mode. A permissive umask or inherited default ACL can leave these directories writable by another local user, allowing that user to delete an active holder’s claims. Another authorized process can then acquire the lock while the original holder remains in its critical section. An attacker can also plant malformed claims to prevent acquisition. This issue is fixed in version 4.2.1. |
| filelock is a platform-independent file lock for Python. From 3.10.0 until 4.2.1, filelock on Windows ignores the mode argument for WindowsFileLock files and the ReadWriteLock SQLite database. A lock created with mode=0o600 receives the parent directory's inheritable ACL because _open_non_reparse_fd and _nt_open do not create an owner-only security descriptor. Another local account with inherited access can read holder metadata or the lock database, modify those files where the ACL permits writes, or take the byte-range lock after release and delay later acquisitions. UnixFileLock is not affected, and mutual exclusion between cooperating processes continues to hold. This issue is fixed in version 4.2.1. |

Since rescue mount options will mark the full fs read-only, there should
be no new transaction triggered.
But during unmount we will evict all inodes, which can trigger a new
transaction, and triggers warnings on a heavily corrupted fs.
[CAUSE]
Btrfs allows new transaction even on a read-only fs, this is to allow
log replay happen even on read-only mounts, just like what ext4/xfs do.
However with rescue mount options, the fs is fully read-only and cannot
be remounted read-write, thus in that case we should also reject any new
transactions.
[FIX]
If we find the fs has rescue mount options, we should treat the fs as
error, so that no new transaction can be started. |
| A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations. |
