CVE-2026-97526

A vulnerability in the Linux kernel (s390/pai) allows for a kernel panic when CPUs are hotplugged during a perf stat command execution, specifically using pai_crypto/CRYPTO_ALL/. The root cause is the missing allocation of per-CPU data structures for newly added CPUs; the existing dynamic allocat...

CVE-2026-93208

The Linux kernel contains a race condition in KASAN involving cache shrinking and CPU hotplug . Specifically, kmem_cache_shrink() fails to hold the cpus_read_lock(), allowing a race where objects are moved to a CPU's shrink_qlist just before that CPU goes offline. Because the offline CPU's list i...
