CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: A potential memory leak has been fixed in ext4fcrecordregions. Since krealloc may return NULL, in this case, state-fcregions may not be freed by krealloc. However, state-fcregions is already set to NULL. This could lead to ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfs: Handling of failures in nfsgetlockcontext during unlock path When memory is insufficient, the allocation of nfslockcontext in nfsgetlockcontext fails and returns -ENOMEM. If we mistakenly treat an nfs4unlockdata structure...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: backlight: pm8941: Add a NULL check in wledconfigure. The devmkasprintf function returns NULL when memory allocation fails. Currently, wledconfigure does not check for this case, resulting in a NULL pointer being dereferenced. Ad...

CVE-2026-74728

CVE-2026-74728 is a NULL pointer dereference in the Linux kernel's XFS filesystem repair tooling. When xfs_buf_alloc_backing_mem() fails, xfs_buf_free() is called with bp->b_addr still NULL. The code then falls through to the folio_put path, which calls virt_to_folio(NULL), dereferencing an in...

CVE-2026-72252

A flaw was found in the Linux kernel. A memory allocation failure during network filter operations can lead to an inconsistent state within the netfilter: nftsetpipapo module. This inconsistency can result in out-of-bounds writes, which may allow a local attacker to cause a system crash denial of...

CVE-2026-72457

A flaw was found in the AppArmor security module within the Linux kernel. During the unpacking of security policies, a memory allocation failure for the ACCEPT2 table was not handled correctly. This could result in an incomplete security policy being loaded, potentially leading to a bypass of...

389-ds-base: 389-ds-base: NULL pointer dereference in deref control plugin BER parser

A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure...

CVE-2026-74448

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix QID bit leak in pqmcreatequeue When MES is enabled and amdgpuamdkfdallockernelmem fails during the first queue creation for a process, pqmcreatequeue returns early via 'return retval' without going through the...

CVE-2026-74448

CVE-2026-74448 affects the Linux kernel’s DRM/amdkfd path. When MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process, pqm_create_queue() may return early via a plain return, skipping the error cleanup and leaving a reserved QID bit set in queue_s...

CVE-2026-74442 drm/vmwgfx: avoid destroy_workqueue(NULL) on vkms init failure

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: avoid destroyworkqueueNULL on vkms init failure Two paths through vmwvkmsinit can leave vmw-crcworkq NULL while still leaving the rest of the driver in a state that calls vmwvkmscleanup at module unload: 1...

CVE-2026-72316 dm era: fix NULL pointer dereference in metadata_open()

In the Linux kernel, the following vulnerability has been resolved: dm era: fix NULL pointer dereference in metadataopen metadataopen returns NULL when kzallocobj fails, but the caller eractr only checks ISERRmd. Since ISERRNULL returns false, the NULL pointer is treated as a valid result and lat...

CVE-2026-72316

In the Linux kernel vulnerability CVE-2026-72316, the metadata_open() path used by device-mapper metadata handling returns NULL on kzalloc_obj() failure, but era_ctr() only checks IS_ERR(md). Since IS_ERR(NULL) is false, a NULL is treated as valid and later dereferenced (era->md). The fix is t...
