Description OSIDB Bzimport 2025-05-08 07:02:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: typec: class: Fix NULL pointer access

Concurrent calls to typec_partner_unlink_device can lead to a NULL pointer
dereference. This patch adds a mutex to protect USB device pointers and
prevent this issue. The same mutex protects both the device pointers and
the partner device registration.
