CVE-2026-90046

CVE-2026-90046 is a Linux kernel vulnerability in the mm/page_alloc subsystem where free_pages_nolock() uses spin_trylock() in NMI context on UP (uniprocessor) builds, an unsafe usage previously noted in can_spin_trylock(). A prior commit fixed the allocation side but missed the free side. The im...
