In bnep_rx_frame() and bnep_ctrl_frame() (net/bluetooth/bnep/core.c),\n   use pskb_may_pull() to verify the BNEP header, control type byte,\n   filter count, and extension headers exist before reading them, and\n   return 0 after handling BNEP_CONTROL instead of falling through to\n   Ethernet frame submission when no extension headers follow.\n2. In bnep_net_xmit() (net/bluetooth/bnep/netdev.c), verify skb->len >=\n   ETH_HLEN with pskb_may_pull() before reading the 14-byte Ethernet\n   header to prevent an out-of-bounds heap read and infoleak on short\n   AF_PACKET TX frames.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
