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 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s drivers/gpu/drm/msm/msmgemsubmit.c code, specifically in the submitlookupcmds function. This flaw occurs because there is no check on the return value of kmalloc. This issue allows a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mm/slub: Fixed the issue by returning errno if kmalloc fails. In createuniqueid, kmalloc, GFPKERNEL may fail due to out-of-memory conditions. If this happens, errno should be returned correctly instead of triggering a panic via...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: Handling of integer overflows in kmallocreserve The committed change was as follows: c ptr = kmallocsize; if ptr size = ksizeptr; size = kmallocsizeroundupsize; ptr = kmallocsize; This caused various crashes, as reported ...

Astra Linux – Vulnerability in Linux, Linux 5.10

A issue was discovered in the Linux kernel through version 5.16-rc6. The function uapifinalize in drivers/infiniband/core/uverbsuapi.c lacks a check for the function kmallocarray...

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...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: udmabuf: validate ubuf-pagecount Syzbot reported a GPF in sgallocAppendTableFromPages. The problem lies in ubuf-pages == ZEROPTR. ubuf-pagecount is calculated based on arguments passed from user-space. If the user creates an...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for a potential null return from kmallocarray. Since kmallocarray may return null, the use of 'eventwaitersi.wait' could lead to a null pointer derefrence. Therefore, it is better to check the return value of...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: In the tty module, a deadlock caused by calling printk under ttyport-lock was fixed. The ptywrite function invokes kmalloc, which may invoke a regular printk call to print failure messages. This can lead to a deadlock in the...

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

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...
