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...
