Medium (5.5) in linux linux kernel. EPSS 0.1% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: Fix Oops by 9.1 surround channel names
get_line_out_pfx() may trigger an Oops by overflowing the static array
with more than 8 channels. This was reported for MacBookPro 12,1 with
Cirrus codec.
As a workaround, extend for the 9.1 channels and also fix the
potential Oops by unifying the code paths accessing the same array
with the proper size check.
