CVE-2026-64477

CVE-2026-64477 affects Linux kernel (x86, fs/resctrl) where offlining a CPU with SNC enabled can trigger an out-of-bounds access. The root cause is that when a monitoring domain’s cpu_mask becomes empty, the NUMA node lookup uses nr_cpu_ids, leading to out-of-bounds during RMID reading. The mitig...

CVE-2026-46281

CVE-2026-46281 affects the Linux kernel vmalloc path used by vrealloc when a new allocation is forced (wrong NUMA node or alignment). The code copies old_size bytes into a newly allocated buffer of size bytes during a shrink request, which can cause an out-of-bounds write. The fix bounds the copy...
