Linux Kernel Intel ASoC SDW Array Termination Vulnerability

A vulnerability in the Linux kernel's ASoC Intel SDW component has been addressed. The issue arose because the code relied on an initialized member of the asoc_sdw_dailink structure to check if an array member was in use. This approach led to an out-of-bounds access when the array was full. The vulnerability has been resolved by expanding the array to include a terminator, preventing the access beyond the array's end.

Impact

Exploitation of this vulnerability could lead to out-of-bounds memory access, potentially causing undefined behavior or memory corruption.
