In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
Bluetooth: bnep: fix out-of-bounds reads on short RX\/TX frames and control fallthrough<\/p>\n
Fix multiple out-of-bounds reads in Bluetooth BNEP frame processing:<\/p>\n
1. 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
