CVE-2025-38368

Local system crash via unchecked device-name allocation

Published Jul 25, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel allows local users to crash the system during TPS6594 PFSM device probing. In tps6594_pfsm_probe(), devm_kasprintf() can return NULL for pfsm->miscdev.name, and the probe path uses that unchecked pointer. Triggering the fault requires local low-privileged access and the TPS6594 PFSM driver probe path; the documented consequence is a service-interrupting kernel crash.
