How to fix?

Upgrade Ubuntu:26.04 sudo to version 1.9.17p2-1ubuntu3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Ubuntu. See How to fix? for Ubuntu:26.04 relevant fixed versions and status.

Sudo through 1.9.17p2 fails to apply intercept policy checks to the execveat system call in ptrace-based intercept mode. Users permitted to run specific commands can execute denied programs by calling execveat directly or through fexecve, bypassing policy enforcement and logging.
