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,...
