In the Linux kernel, the following vulnerability has been resolved:
ALSA: gus: fix null pointer dereference on pointer block
The pointer block return from snd_gf1_dma_next_block could be
null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference.
