Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of kmalloc when low memory conditions occur, resulting in the mutual locking mechanis...

CVE-2026-45959: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree Annotating a local pointer variable, which will be assigned with the kmalloc-family functions, with the cleanupkfree attribute will make the address of the local...

PT-2026-43846

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: clean up the amdgpu cs parser bos In low memory conditions, kmalloc can fail. In such conditions unlock the mutex for a clean exit. We do not need to amdgpu bo list put as it's been handled in the amdgpu cs parser fin...

CVE-2025-71312: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix ntfsmountoptions leak in ntfsfillsuper In ntfsfillsuper, the fc-fsprivate pointer is set to NULL without first freeing the memory it points to. This causes the subsequent call to ntfsfsfree to skip freeing the...

PT-2026-43896

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description On Uniprocessor UP kernels where CONFIG SMP is not enabled, the spin trylock function acts as a no-op and unconditionally succeeds. This allows kmalloc nolock called from a Non-Maskable...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/migrate: prevents infinite recursion. If the buf + offset is not aligned to XECAHELINEBYTES, we fall back to using a bounce buffer. However, the bounce buffer is allocated on the stack, and the only alignment requirement...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: slab: fixed the context check for kmallocnolock in the PREEMPTRT kernel mode. In PREEMPTRT kernels, locallock acts as a sleeping lock. The current check in kmallocnolock only verifies that the context does not match NMI or hard I...

SUSE CVE-2026-43330

In the Linux kernel, the following vulnerability has been resolved: crypto: caam - fix overflow on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache alignment, as otherwi...

CVE-2026-43330

CVE-2026-43330 relates to the Linux kernel crypto/caam path, where an overflow occurs when a long HMAC key (longer than the block size) is copied for hashing. The vulnerability arises because the copy’s allocated memory is aligned for DMA, and the original kmemdup path could read beyond the key b...

CVE-2026-43245

In the Linux kernel, the following vulnerability has been resolved: ntfs: -dcompare must not block ... so don't use getname there. Switch it and ntfsdhash, while we are at it to kmallocPATHMAX, GFPNOWAIT. Yes, ntfsdhash almost certainly can do with smaller allocations, but let ntfs folks deal wit...

CVE-2026-43245 ntfs: ->d_compare() must not block

In the Linux kernel, the following vulnerability has been resolved: ntfs: -dcompare must not block ... so don't use getname there. Switch it and ntfsdhash, while we are at it to kmallocPATHMAX, GFPNOWAIT. Yes, ntfsdhash almost certainly can do with smaller allocations, but let ntfs folks deal wit...

CVE-2026-43245

CVE-2026-43245 affects the Linux kernel NTFS driver. The root cause is that ntfs: ->d_compare() could block, with related memory-allocation issues in names_cachep. The authenticated fixes switch critical paths to non-blocking allocations: use kmalloc(PATH_MAX, GFP_NOWAIT) for the path/name han...

PT-2026-37585

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the NTFS driver where the d compare function improperly blocks due to the use of getname. To resolve this, the implementation was switched to use kmallocPATH MAX, GFP...

AZL-83837 CVE-2026-31669 affecting package kernel for versions less than 6.6.137.1-1

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix slab-use-after-free in inetlookupestablished The ehash table lookups are lockless and rely on SLABTYPESAFEBYRCU to guarantee socket memory stability during RCU read-side critical sections. Both tcpprot and tcpv6prot ha...
