CVE-2022-50660

Kernel memory leak via unreleased driver allocations

Published Dec 9, 2025 · Updated May 11, 2026

A memory leak in the ipw2200 wireless driver in Linux allows attackers to leave kernel memory allocated via unspecified vectors. The ipw_wdev_init error path returns without releasing its allocated wireless device, and ipw_pci_probe likewise omits a release on a probe failure. The public record does not identify who can force these initialization failures, whether they can be repeated, or whether the leak interrupts service.
