CVE-2024-50197

Local service interruption via leaked child-node reference

Published Nov 8, 2024 · Updated May 11, 2026

Memory leak in Linux 6.8 through 6.11.4 allows local users to exhaust kernel memory through an Intel pinctrl error path. An early return in intel_platform_pinctrl_prepare_community omits fwnode_handle_put, leaving the parsed child node's reference count elevated. Triggering requires local low-privilege access and the driver's error path; repeated triggers can interrupt service through memory exhaustion.
