Description OSIDB Bzimport 2024-08-26 08:20:30 UTC

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

Bluetooth: MGMT: Add error handling to pair_device()

hci_conn_params_add() never checks for a NULL value and could lead to a NULL
pointer dereference causing a crash.

Fixed by adding error handling in the function.
