Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:

Specifically, UAC3 cluster segment descriptors require validation to ensure their sizes align with declared lengths and allocated buffer sizes. Insufficient validation can lead to out-of-bounds (OOB) access triggered by malicious firmware.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
