CVE-2023-53757

Resource leak via unreleased parent-node reference

Published Dec 8, 2025 · Updated May 11, 2026

Resource leak in the irq-mvebu-gicp driver in Linux 4.13 through affected branch versions allows attackers unspecified impact via unspecified vectors. The mvebu_gicp_probe function obtains a parent interrupt-controller node with of_irq_find_parent(), which increments its reference count, but fails to call of_node_put() after the node is no longer needed. The flaw occurs during GICP driver probing; published Linux material does not establish attacker control over the probe path or a resulting operational consequence.
