ASoC: amd: acp-sdw-legacy: Bound DAI link iteration
Overview
Description

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.
