| In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/gsp: add SEC2 to GA100 chip table
The booter-load and booter-unload firmware run on the SEC2 falcon.
During tu102_gsp_oneinit(), the booter constructor needs device->sec2
to access the SEC2 falcon.
Without the .sec2 entry, device->sec2 is NULL and this dereference
crashes during GSP-RM boot. |
| A NULL pointer dereference in the gf_filter_pid_resolve_file_template_ex function (/filter_core/filter_pid.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted file. |
| GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing.
An attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service.
This issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313 |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: don't enable large folios on encrypted inodes
Commit 709f0f1f1bf5 ("ext4: add checks for large folio
incompatibilities when BS > PS") disables large folios at mount time
if the "encrypt" feature is set. However, enabling that feature on a
mounted filesystem circumvents that check, and writing encrypted data
results in a crash:
BUG: kernel NULL pointer dereference, address: 0000000000000028
Workqueue: ext4-rsv-conversion ext4_end_io_rsv_work
RIP: 0010:ext4_finish_bio+0xf7/0x3e0
Call Trace:
ext4_release_io_end+0x51/0x110
ext4_end_io_end+0x4c/0xe0
ext4_end_io_rsv_work+0xb3/0x100
Fix this by disabling large folios on encrypted inodes, as is
already done for inodes that use data journaling.
This affects all kernels between v6.19 and v7.2, but it is not needed
in v7.3, where the code was significantly refactored. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/vm: nuke PTs only after unlinking contested VMAs
In xe_vm_close_and_put(), external-BO VMAs are queued on the contested
list for deferred destruction via xe_vma_destroy_unlocked(). However,
xe_vm_pt_destroy() was previously invoked before processing contested
VMAs, destroying vm->pt_root while those VMAs were still linked to their
respective buffer objects (vm_bo->list.gpuva).
If a concurrent thread evicts one of those shared buffer objects,
xe_bo_trigger_rebind() holding only bo->resv walks the BO's VMAs and, in
fault mode, calls xe_vm_invalidate_vma() -> xe_pt_zap_ptes(). Because
vm->pt_root[tile->id] is already NULL, dereferencing pt->level causes a
NULL ptr deref.
Fix this by deferring xe_vm_free_scratch() and xe_vm_pt_destroy() until
after all contested VMAs have been unlinked and destroyed.
User is reporting hitting a NULL ptr deref in xe_pt_zap_ptes(), which
could be explained by this race.
(cherry picked from commit c2863648959489767f08892fd6e90577d2ea0b6a) |
| Apache Traffic Server can crash with a null pointer dereference when a client POST request is torn down via half-close while a chunked origin response is being reparsed from a reentrant write-ready callback, a timing-dependent race introduced by the CVE-2021-32564 flow-control backports.
This issue affects Apache Traffic Server: 9.2.15, 10.1.4, 10.2.0.
Users are recommended to upgrade to version 9.2.16, 10.1.5, or 10.2.1, which fix the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: reject net_iov in zerocopy receive mapping hints
After copying a readable prefix, receive_fallback_to_copy() asks
tcp_zerocopy_set_hint_for_skb() where page mapping can resume. If the
next skb is unreadable, find_next_mappable_frag() passes its net_iov
fragment to can_map_frag().
skb_frag_page() returns NULL for a net_iov, but can_map_frag()
dereferences it in PageCompound(). A v7.2 KASAN run on a connected TCP
socket with 64 readable bytes followed by a 4096-byte NET_IOV_DMABUF
fragment reported:
BUG: KASAN: null-ptr-deref in can_map_frag
tcp_zerocopy_receive -> can_map_frag
Kernel panic - not syncing: KASAN: panic_on_warn set
The diagnostic inserted the net_iov directly because the test host has
no devmem-capable NIC. Hardware end-to-end reachability remains untested
and requires CONFIG_NET_DEVMEM plus a supported DMA-buf-bound RX queue.
Reject all net_iov fragments before skb_frag_page(). This covers both
DMABUF and IOURING net_iov types while leaving page-backed checks
unchanged. With the guard, the same queue copied the readable prefix,
returned a 4096-byte skip hint, and completed without a fault. |

This bug showed up starting with v7.3-rc1. At the NIP in
phy_link_topo_add_phy() is a netdev_need_ops_lock() check.
This was added by the following
commit ded86da4bbb7 ("net: ethtool: relax ethnl_req_get_phydev() locking assertion")
The bug shows up because at the time of_phy_connect() was called, the
netdev_ops were *not yet* determined. My fix is to move the code that
sets netdev_ops+commac.ops+ethtool_ops further up as emac_init_config()
derives that by looking at the device-tree and sets the required
dev->phy_mode accordingly.
During review, the Sashiko bot's AI stated that the commac assignment
became a dead store. Great catch! To keep the original behavior as-is,
one mentioned option "set dev->commac.ops = &emac_commac_ops only in
the non-gige case?" sounded like a great plan. So the dev->commac.ops
assignment for the non-gige-case moves into the else block.
This patch was tested on a WD MyBook Live (RGMII). the device now works again. |
| pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, ixmlNode_compare in ixml/src/node.c passes the nullable nodeValue, namespaceURI, prefix, and localName fields directly to strcmp. Non-namespaced attributes created by ixmlDocument_createAttribute legitimately leave those fields NULL. When ixmlElement_removeAttributeNode compares two distinct attribute objects with the same nodeName through find_condition_node, the pointer-identity shortcut does not apply and the comparison dereferences NULL, causing a process crash when application handling of attacker-controlled XML reaches this path. This issue is fixed in 2.0.2. |
| kin-openapi is a Go project for handling OpenAPI files. Prior to 0.145.0, openapi3.Loader can dereference a nil SchemaRef.Value while resolving a self-referential additionalProperties JSON Reference such as a schema that points to its own additionalProperties member. Loading an attacker-controlled OpenAPI document through LoadFromData, LoadFromFile, or LoadFromURI reaches resolveComponent before document validation and can panic the loading process. Resolved additionalProperties schemas and ordinary recursive schemas do not take the vulnerable nil-value path. This issue is fixed in version 0.145.0. |
| kin-openapi is a Go project for handling OpenAPI files. Prior to 0.146.0, openapi3filter.ValidateResponse passes a nil response header schema to decodeValue when an OpenAPI document declares the header with content instead of schema. The document passes validation, but every response validation for the affected operation dereferences the nil schema and panics even when the response does not contain the declared header. Applications that ingest an untrusted specification can expose this as remote availability impact, while applications using only trusted local specifications still crash when the affected operation is exercised. This issue is fixed in version 0.146.0. |
| kin-openapi is a Go project for handling OpenAPI files. Prior to 0.148.0, the OpenAPI 3.1 validation path passes YAML NaN and infinity numeric values to santhosh-tekuri/jsonschema v6.0.2 without applying kin-openapi's existing finite-number guards. A remote unauthenticated client can send an application/yaml or application/x-yaml request body containing .nan, .inf, or -.inf to an operation with a numeric constraint, causing the dependency to create and dereference a nil big.Rat during ValidateRequest. Standard net/http servers recover the panic per connection, while other hosts or application goroutines may terminate the process. This issue is fixed in version 0.148.0. |
| The ONVIF service on the E3 can be rendered unresponsive by sending malformed or incomplete requests to certain operations. The affected service stops accepting new connections while the rest of the device continues operating normally, and will recover automatically after a period. This can be triggered repeatedly by any unauthenticated party with network access to the device. |
| libIEC61850 is an open-source implementation of IEC 61850 client and server protocols including MMS, GOOSE, Sampled Values, and R-Session. Prior to 1.6.2, alternateArrayAccess in src/mms/iso_mms/server/mms_read_service.c does not validate an alternate-access sub-array range when numberOfElements is greater than zero. An out-of-range MmsValue_getElement call returns NULL, and the sub-array branch passes that value to MmsValue_isDeletable, causing a NULL pointer dereference. A remote MMS Read request can therefore crash servers whose data models contain arrays, while the single-element error path handles the same invalid index safely. This issue is fixed in version 1.6.2. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: release layout stid on setlease failure
nfs4_alloc_stid() publishes the new stid into cl->cl_stateids via
idr_alloc_cyclic() under cl_lock before returning to
nfsd4_alloc_layout_stateid(). When nfsd4_layout_setlease() then
fails, the error path frees the layout stateid directly with
kmem_cache_free() without ever calling idr_remove(), leaving the
IDR slot pointing at freed slab memory. Any subsequent IDR walker
(states_show, client teardown) dereferences the dangling pointer.
The correct teardown for an IDR-published stid is nfs4_put_stid(),
which removes the IDR slot under cl_lock, dispatches sc_free
(nfsd4_free_layout_stateid) to release ls->ls_file via
nfsd4_close_layout(), and drops the nfs4_file reference in its
tail.
A second issue blocks that switch: nfsd4_free_layout_stateid()
unconditionally inspects ls->ls_fence_work via
delayed_work_pending() under ls_lock, but
INIT_DELAYED_WORK(&ls->ls_fence_work, ...) currently runs only
after the setlease call. On the setlease-failure path the
destructor would touch an uninitialized delayed_work.
nfsd4_alloc_layout_stateid()
nfs4_alloc_stid() /* idr_alloc_cyclic under cl_lock */
nfsd4_layout_setlease() /* fails */
nfs4_put_stid()
nfsd4_free_layout_stateid()
delayed_work_pending(&ls->ls_fence_work) /* needs INIT */
nfsd4_close_layout() /* nfsd_file_put(ls->ls_file) */
put_nfs4_file()
Fix by hoisting the ls_fenced / ls_fence_delay / INIT_DELAYED_WORK
initialization above the nfsd4_layout_setlease() call, and replace
the manual nfsd_file_put + put_nfs4_file + kmem_cache_free cleanup
with a single nfs4_put_stid(stp). |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Do not clear VM-wide SVE feature on vCPU init failure
pkvm_vcpu_init_sve() clears KVM_ARM_VCPU_SVE in kvm->arch.vcpu_features
when it fails, but vcpu_has_sve() tests KVM_ARCH_FLAG_GUEST_HAS_SVE,
which is left set. Later vCPUs on that VM then skip the SVE setup and
register with a NULL sve_state, which the guest's first FP access hands
to sve_load_state().
Return the error without touching vcpu_features. |
| In the Linux kernel, the following vulnerability has been resolved:
eth: fbnic: reset num_napi when the napi vectors are freed
fbn->num_napi is the count of live napi vectors, each of which owns an
IRQ. The PM path had freed them without clearing the count.
fbnic_pm_suspend() tears the datapath down via ndo_stop() and frees the
IRQs, but leaves netif_running() true so resume knows to re-open. Resume
rebuilds the datapath in __fbnic_pm_resume() and fbnic_reset_queues() sets
num_napi and __fbnic_open() re-allocates the vectors.
When the datapath is torn down but never rebuilt, num_napi is left
pointing at freed vectors under 2 different scenarios:
- a PCIe error recovery that fails (fbnic_err_slot_reset() ->
__fbnic_pm_resume() returns an error -> PCI_ERS_RESULT_DISCONNECT), so
.resume never runs; or
- an __fbnic_open() that fails partway on resume and unwinds, freeing
the vectors after fbnic_reset_queues() has already set num_napi.
The netdev is then running with num_napi > 0 but napi[] freed, and the
eventual remove/unbind close re-enters fbnic_down() -> fbnic_dbg_down()
and dereferences the freed vectors:
BUG: kernel NULL pointer dereference, address: 0000000000000210
RIP: fbnic_dbg_down+0x28
Clear num_napi when the vectors are freed: in the suspend teardown (a
good resume re-establishes it before __fbnic_open()) and on the resume
open failure. A redundant ndo_stop() then walks an empty napi[]. The
normal ndo_stop() down/up cycle is untouched and keeps num_napi for the
next ndo_open(). |
| A NULL Pointer Dereference vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a configured peer sending a BGP UPDATE to cause a denial of service when an import policy with `then source-based-forwarding next-hop next-table <X>` is configured to reference a routing table that does not exist. |
| yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.1, JNI-backed XXHash implementations fail to validate the byte array object and the off and len arguments in XXHashFactory.nativeInstance().hash32().hash(), XXHashFactory.nativeInstance().hash64().hash(), XXHashFactory.nativeInstance().newStreamingHash32().update(), and XXHashFactory.nativeInstance().newStreamingHash64().update(), allowing null arrays or oversized ranges to reach native code, read outside the Java array, and fatally terminate the JVM. This issue is fixed in version 1.11.1. |
