Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
Bluetooth: hci_core: Fix UAF in hci_unregister_dev()<br />
<br />
hci_unregister_dev() does not disable cmd_timer and ncmd_timer<br />
before the hci_dev structure is freed. If a timeout fires<br />
during device teardown, the callback dereferences freed memory<br />
(including the hdev->reset function pointer), leading to a<br />
use-after-free.<br />
<br />
Add disable_delayed_work_sync() calls alongside the existing<br />
disable_work_sync() calls to ensure both timers are fully<br />
quiesced before teardown proceeds.
