Vulnerability Title
ASoC: amd: acp-sdw-sof: Bound DAI link iteration
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp-sdw-sof: Bound DAI link iteration create_sdw_dailinks() walks sof_dais until it finds an entry with initialised cleared, but sof_dais is allocated with exactly num_ends entries. If all entries are initialised, the loop reads past the end of the array. Pass the allocated entry count to create_sdw_dailinks() and stop before reading past the array.
