CVE-2024-57930

Local service interruption via trace validation false positive

Published Jan 21, 2025 · Updated May 11, 2026

Denial of service in Linux kernel tracing allows local users to cause an unspecified service interruption through event registration. process_string() incorrectly rejects safe %s references into arrays indexed by trace-record fields, causing test_event_printk() to report a false positive. Low-privileged local access is required; Linux has not published whether the resulting interruption is a hang, crash, reboot, or shutdown.
