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

Description A use-after-free issue exists in the FarSync T-series card driver. When the card is detached, the fst card info structure is deallocated in the fst remove one() function. However, if fst tx task or fst int task are still running or pending, they may attempt to access the freed fst card info within the fst process tx work q() or fst process int work q() functions, leading to a system crash.

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