CVE-2026-64288

CVE-2026-64288 fixes a race/NULL-pointer dereference in KVM ARM64 VNCR pseudo-TLB invalidation. The vulnerability arises when VNCR TLB invalidation can race with a vCPU coming online/offline, potentially dereferencing an unallocated VNCR, leading to a crash. The Linux kernel patches introduce a n...
