CVE-2024-50204

Local service interruption via invalid rbtree removal

Published Nov 8, 2024 · Updated May 11, 2026

Denial of service in Linux 6.11 through 6.11.5 allows local users to interrupt kernel operation via a failed namespace copy. The copy-failure path calls free_mnt_ns() before the new namespace node enters the rbtree, causing cleanup to erase an unlinked node. Low-privilege local access and a mount-namespace copy failure are required; published sources do not specify whether the result is a hang, crash, or reboot.
