CVE-2026-80620

A flaw was found in the Linux kernel. During the error handling of Message Signaled Interrupts eXtended MSI-X region setup, the kernel attempts to unmap an already freed memory region. This double unmap operation on a null pointer can lead to a kernel warning or crash. A local attacker could...
