A flaw was found in the ALSA pcxhr driver within the Linux kernel. The pcxhr_probe() function requests a threaded interrupt before properly initializing a critical mutex (mgr->lock). This oversight could allow an early interrupt to operate on an uninitialized mutex, potentially leading to system instability or a denial of service (DoS) condition. A local attacker could potentially exploit this to impact system availability.
