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

Description: The issue is related to a potential use-after-free case in the tcpm register source caps() function. This could happen when new source caps are advertised, existing source caps are unregistered, and tcpm register source caps() returns with an error due to usb power delivery register capabilities() failing. As a result, port->partner source caps holds on to the now freed source caps. The problem can be resolved by resetting the port->partner source caps value to NULL after unregistering existing source caps.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
