Linux kernel is vulnerable to memory corruption vulnerability. This is because the ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently causing an out-of-bounds access.
