Description
A flaw was found in the Linux kernel's audio subsystem. The STI audio driver registers a shared interrupt request (IRQ) before initializing its internal locking mechanism. A local attacker capable of triggering driver initialization may cause an interrupt to be handled while the lock remains uninitialized. This issue can crash the kernel, resulting in a denial of service (DoS).
