AI-suggested
A fix has been implemented by adding error handling in the pair_device() function. Users should apply the official Linux kernel updates that include this fix.
Description
CVE-2024-43884 is a vulnerability in the Linux kernel's Bluetooth management subsystem where the function hci_conn_params_add() does not check for NULL values, potentially leading to a NULL pointer dereference and causing a system crash. The issue was fixed by adding proper error handling in the pair_device() function.
