In the Linux kernel, the following vulnerability has been resolved:
ASoC: amd: acp-sdw-legacy: Bound DAI link iteration
create_sdw_dailinks() walks soc_dais until it finds an entry with
initialised cleared, but soc_dais is allocated with exactly num_ends
entries. If all entries are initialised, the loop reads past the end of
the array.
This was reported by KASAN:
BUG: KASAN: slab-out-of-bounds in mc_probe+0x26b3/0x2774 [snd_acp_sdw_legacy_mach]
Read of size 1
Pass the allocated entry count to create_sdw_dailinks() and stop before
reading past the array.
