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.
