Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: hdmi-codec: Fix OOB memory accesses
Correct size of iec_status array by changing it to the size of status
array of the struct snd_aes_iec958. This fixes out-of-bounds slab
read accesses made by memcpy() of the hdmi-codec driver. This problem
is reported by KASAN.
