CVE-2023-53613

Kernel memory corruption via premature DAX parent release

Published Oct 4, 2025 · Updated Oct 4, 2025

Use-after-free in Linux kernel DAX device teardown allows local users to corrupt kernel memory while removing a device-DAX provider. dax_mapping_release() calls ida_free() through a parent dev_dax object that can already be released because the child mapping did not retain it. Reaching the faulty release path requires local low-privileged access and device-DAX provider removal; the published reproducer reports a lockdep warning, not demonstrated privilege gain.
