CVE-2026-58093

Name of the Vulnerable Software and Affected Versions The product name cannot be determined (affected versions not specified)

Description A race condition exists in the TIOCSCTTY ioctl handler. The handler releases the tty lock to acquire the process tree lock but fails to revalidate the terminal state after reacquiring the tty lock. This allows a terminal being concurrently destroyed to be linked to the calling process session, enabling an unprivileged local user to escalate privileges.

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