CVE-2026-46029

A flaw was found in the Linux kernel. In uniprocessor UP kernel configurations, a race condition can occur within the slab memory allocator when kmallocnolock is invoked from a Non-Maskable Interrupt NMI context. This allows the allocator to attempt to acquire a spinlock that is already held,...

CVE-2026-46035

A flaw was found in the Linux kernel's memory management subsystem. On uniprocessor UP kernels, a Non-Maskable Interrupt NMI can cause the allocfrozenpagesnolock function to re-enter rmqueue and acquire a zone lock that is already held by an interrupted process. This can lead to corruption of the...

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...
