CVE-2026-74667

A flaw was found in the Linux kernel's networking packet handling. Specifically, the packetparseheaders function does not consistently reset the Media Access Control MAC header for certain packet types on the PACKETQDISCBYPASS path. This can lead to an unset MAC header, causing a driver to perfor...

CVE-2026-74667

CVE-2026-74667 is an out-of-bounds read in the Linux kernel's net/packet subsystem. The packet_parse_headers() function fails to reset skb->mac_header for protocol-bound SOCK_RAW sockets, SOCK_DGRAM frames, and the legacy SOCK_PACKET path. When these frames traverse the PACKET_QDISC_BYPASS tra...

CVE-2026-72019

CVE-2026-72019 affects the Linux kernel macsec path: macsec_encrypt() reads the Ethernet header via eth_hdr(skb) when skb->mac_header is unset on AF_PACKET SOCK_RAW + PACKET_QDISC_BYPASS, causing a 12-byte heap over-read and the frame’s outer MAC to be read on the wire. The issue occurs becaus...

CVE-2022-48651

In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused by unset skb-macheader If an AFPACKET socket is used to send packets through ipvlan and the default xmit function of the AFPACKET socket is changed from devqueuexmit to packetdirectxmit via...

CVE-2022-48651 ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header

In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fix out-of-bound bugs caused by unset skb-macheader If an AFPACKET socket is used to send packets through ipvlan and the default xmit function of the AFPACKET socket is changed from devqueuexmit to packetdirectxmit via...

CVE-2022-48651

CVE-2022-48651 affects the Linux kernel ipvlan path. When an AF_PACKET socket uses PACKET_QDISC_BYPASS and the default xmit path is switched, skb->mac_header may remain at 65535, yielding slab-out-of-bounds in ipvlan_xmit_mode_l2. Root causes: packet_snd() only resets skb->mac_header for SO...
