Details

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.

Severity ?

5.5 (Medium)
