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

Bluetooth: bnep: fix out-of-bounds reads on short RX/TX frames and control fallthrough

Fix multiple out-of-bounds reads in Bluetooth BNEP frame processing:

In bnep rx frame() and bnep ctrl frame() (net/bluetooth/bnep/core.c), use pskb may pull() to verify the BNEP header, control type byte, filter count, and extension headers exist before reading them, and return 0 after handling BNEP CONTROL instead of falling through to Ethernet frame submission when no extension headers follow.
In bnep net xmit() (net/bluetooth/bnep/netdev.c), verify skb->len >= ETH HLEN with pskb may pull() before reading the 14-byte Ethernet header to prevent an out-of-bounds heap read and infoleak on short AF PACKET TX frames.
