In the Linux kernel, the following vulnerability has been resolved:

class: fix use-after-free in class_register()

The lock_class_key is still registered and can be found in lock_keys_hash hlist after subsys_private is freed in error handler path.A task who iterate over the lock_keys_hash later may cause use-after-free.So fix that up and unregister the lock_class_key before kfree(cp).

On our platform, a driver fails to kset_register because of creating duplicate filename '/class/xxx'.With Kasan enabled, it prints a invalid-access bug report.

WID-SEC-W-2024-0475 — Linux-Kernel: Mehrere Schwachstellen ermöglichen Denial of Service und unspezifische Angriffe

2026-10-04T04:12:19.401766+00:00

Ein lokaler Angreifer kann mehrere Schwachstellen im Linux-Kernel ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen oder einen nicht spezifizierten Angriff durchzuführen.
