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...

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...

CVE-2026-46093

CVE-2026-46093 affects the Linux kernel mm/vmalloc subsystem. The issue arises because decay_va_pool_node() can be invoked concurrently from two paths—the purge path and the shrinker path via vmap_node_shrink_scan—without proper serialization. This leads to races and potential memory leaks. The d...

CVE-2026-45853

The CVE-2026-45853 issue is in the Linux kernel drm/amdgpu component. The function amdgpu_discovery_get_nps_info() allocates memory for ranges with kvcalloc() (potentially vmalloc), but frees it with kfree(), which may corrupt vmalloc memory. The documented fix is to use kvfree() to safely handle...
