CVE-2024-49951

Estado: ModificadaMedia (5.5)—

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

Bluetooth: MGMT: Fix possible crash on mgmt_index_removed

If mgmt_index_removed is called while there are commands queued on cmd_sync it could lead to crashes like the bellow trace:

So while handling mgmt_index_removed this attempts to dequeue commands passed as user_data to cmd_sync.
