CVE-2023-53849

Memory leak via uncleared bind workqueue

Published Dec 9, 2025 · Updated May 23, 2026

Memory leak in the Linux kernel msm DRM driver retains a workqueue after a failed device bind instead of freeing it. In msm_drm_bind(), early failures after workqueue allocation reach device cleanup without destroying that workqueue, leaving the allocation behind. The condition requires the msm DRM driver to bind and a subcomponent to fail; public sources establish neither attacker control of that failure nor a resulting crash.
