Description
A flaw was found in the Linux kernel's Qualcomm audio driver (LPASS CPU). When configuring digital audio interfaces on certain platforms, the driver uses a hardware port identifier instead of the table index to update playback constraints. This issue causes an out-of-bounds memory write, which can lead to memory corruption and a denial of service (DoS) due to a system crash.
