AI-suggested

A fix is available and has been applied in multiple Linux kernel commits. Users and administrators should update their Linux kernel to a version that includes these commits to remediate the vulnerability. Since this is not a cloud service, manual patching is required.

Description

A vulnerability in the Linux kernel Bluetooth BNEP implementation allows out-of-bounds reads on short RX/TX frames and incorrect control flow due to control fallthrough. The issue affects the processing of BNEP frames and Ethernet headers, potentially leading to heap reads beyond buffer boundaries and information leaks on short AF_PACKET TX frames. The flaw has been fixed in specific Linux kernel commits.
