CVE-2024-50021

Local service interruption via leaked pin references

Published Oct 21, 2024 · Updated May 11, 2026

A reference-count leak in affected Linux kernel revisions allows local users to interrupt service through the Intel ice network driver. ice_dpll_init_rclk_pins calls ice_dpll_get_pins before validating vsi and vsi->netdev, then returns without releasing the acquired pin references. The published record identifies no attacker-controlled path to that abnormal state, so practical triggering conditions remain undisclosed.
