VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.3/6.11-rc5
Description A null pointer dereference issue has been identified in the Linux kernel's Bluetooth functionality, specifically in the hci conn params add() function, which does not check for a NULL value. This could lead to a crash. The issue has been resolved by adding error handling to the pair device() function.
Recommendations To resolve this issue, update the Linux kernel to a version that includes the fix, which is version 4.3/6.11-rc5 or later. As a temporary workaround, consider restricting access to the Bluetooth functionality until a patch is available.
