CVE-2026-64340

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

Description A use-after-free issue exists in the legousbtower USB driver. The problem occurs during a race condition between the release() and disconnect() functions, where mutex unlock() may attempt to access the mutex structure after the lock has been released. Because mutex unlock() is non-atomic and can access the lock object after unlocking, it cannot be used to manage the lifetime of objects directly.

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