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...
