A flaw was found in the Linux kernel's Nouveau graphics driver. This vulnerability allows a local attacker to cause a Denial of Service (DoS) by crashing the system or potentially escalate privileges. During device initialization failures, the driver's error-handling path executes redundant cleanup routines that release already-freed memory. This improper resource cleanup causes a double-free condition, leading to kernel memory corruption.
