CVE-2026-78229

Local arbitrary OS command execution

Published Sep 30, 2026 · Updated Sep 30, 2026

OS command injection in affected PFU Limited Image Scanner Driver for Linux releases allows local users to run arbitrary OS commands. The public advisory does not identify the driver routine, attacker-controlled input, or operation that passes that input to an OS command. Exploitation requires a login to an affected Linux host and advance preparation; the advisory does not establish a network-facing path or the privileges of the executed command.
