CVE-2026-93171Hinoki check available

Unspecified impact via device-initialization double unlock

Published Sep 17, 2026 · Updated Sep 17, 2026

Double unlocking in Linux 7.2 LP5860 initialization allows attackers to cause unspecified impact via an initialization failure. In lp5860_device_init(), failure of lp5860_init_dt() reaches an error label that unlocks an already released mutex. The path requires LP5860 driver initialization to fail; public records do not identify a crash, hang, or attacker-controlled trigger.
