CVE-2026-46035

CVE-2026-46035 affects the Linux kernel on UP (non-SMP) configurations and describes a vulnerability in mm/page_alloc. The issue arises because on UP, spin_trylock() is a no-op and may always succeed even if the lock is held, allowing alloc_frozen_pages_nolock() invoked from NMI to re-enter rmque...
