Description OSIDB Bzimport 2025-02-26 03:15:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_uart: add missing NULL check in h5_enqueue

Syzbot hit general protection fault in __pm_runtime_resume(). The problem
was in missing NULL check.

hu->serdev can be NULL and we should not blindly pass &serdev->dev
somewhere, since it will cause GPF.
