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...
