CVE-2026-62437

A flaw was found in Xen. When a guest virtual machine is terminated, its device model DM can re-establish interrupt request IRQ tracking structures after the initial cleanup. This prevents some of these structures from being properly deallocated, leading to a memory leak. A local attacker with...
