CVE-2024-53068

Kernel memory corruption via premature SCMI name release

Published Nov 19, 2024 · Updated May 11, 2026

Use-after-free in the Linux kernel arm_scmi driver allows local users to affect confidentiality, integrity, and availability during device teardown. __scmi_device_destroy() frees scmi_dev->name before scmi_bus_notifier() passes that stale pointer to strncmp(), producing a slab read after free. Reachability requires an affected kernel with ARM SCMI device setup; public sources do not identify the user action that reaches the teardown path.
