CVE-2023-52694

Resource leakage via discarded driver cleanup

Published May 17, 2024 · Updated May 11, 2026

Resource leakage in affected Linux kernel releases from 5.7 allows local users to deplete resources by unbinding a built-in TPD12S015 driver. The tpd12s015_remove() function carries an __exit annotation, so built-in compilation discards the cleanup routine that driver unbinding must call. The condition requires the driver to be built into the kernel and then unbound; the public record identifies resource leakage but not the leaked resource or exact service-failure mode.
