Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to v4.14.299
Description
A use-after-free issue was discovered in the L2CAP (Logical Link Control and Adaptation Protocol) component of the Bluetooth protocol. This issue is related to the
l2cap reassemble sdu function. The actual impact and attack plausibility have not yet been proven.Recommendations
For Linux Kernel versions prior to v4.14.299, update to version v4.14.299 or later to resolve the issue. As a temporary workaround, consider disabling Bluetooth functionality until a patch is available. Restrict access to the L2CAP protocol to minimize the risk of exploitation.
