In the Linux kernel, the following vulnerability has been resolved: vmalloc: fix buffer overflow in vreallocnodealign Commit 4c5d3365882d "mm/vmalloc: allow to set node and align in vrealloc" added the ability to force a new allocation if the current pointer is on the wrong NUMA node, or if an...

CVE-2026-46281

A flaw was found in the Linux kernel. When shrinking a vmalloc allocation using the vreallocnodealign function, if the requested new size is smaller than the old size, an out-of-bounds write can occur. This memory corruption vulnerability could allow a local attacker to cause a denial of service ...

CVE-2026-46281

The CVE affects the Linux kernel vmalloc path. A buffer overflow could occur in vrealloc_node_align() when reallocating with shrinking, because old_size bytes could be copied into a newly allocated buffer of size 'size' before the fix. The issue arises during need_realloc when a new object is all...

Linux Distros Unpatched Vulnerability : CVE-2026-45853

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - drm/amdgpu: Use kvfree instead of kfree in amdgpugmcgetnpsmemranges amdgpudiscoverygetnpsinfo internally allocates memory for ranges using kvcalloc, which may u...

CVE-2026-45853

A flaw was found in the Linux kernel's drm/amdgpu component. The amdgpudiscoverygetnpsinfo function incorrectly deallocates memory by using kfree instead of kvfree, even when memory was allocated with kvcalloc which may use vmalloc. This improper memory handling can lead to memory corruption. Suc...

SUSE CVE-2026-46093

In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: take vmappurgelock in shrinker decayvapoolnode can be invoked concurrently from two paths: purgevmaparealazy when pools are being purged, and the shrinker via vmapnodeshrinkscan. However, decayvapoolnode is not safe t...

CVE-2026-46093

A flaw was found in the Linux kernel's memory management vmalloc subsystem. The decayvapoolnode function, when invoked concurrently from the shrinker path, lacks proper serialization. This oversight can lead to race conditions, potentially resulting in memory leaks and affecting system stability...
