CVE-2024-38635

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.37

Description The issue is related to an out-of-bounds access in the soundwire cadence component. The code adds an offset to the PDI, presumably to skip the PDI0 and PDI1, which are reserved for BPT. However, this code is incorrect and leads to an out-of-bounds access. A follow-up patch completely removes this useless offset.

Recommendations Update to Linux kernel version 6.6.37 or later to resolve the issue. As a temporary workaround, consider restricting access to the soundwire cadence component until a patch is available.
