CVE-2026-74582

A race condition in the Linux kernel's packet socket layer affects the non-ring send paths in packet_snd() and packet_sendmsg_spkt(). Both functions read dev->hard_header_len multiple times during skb allocation and construction. If a concurrent device reconfiguration (e.g., a bonding type cha...

CVE-2026-72019

A flaw was found in the macsec component of the Linux kernel. When processing packets on the AFPACKET SOCKRAW + PACKETQDISCBYPASS transmit path, the macsecencrypt function attempts to read an unset Media Access Control MAC header. This leads to a 12-byte heap over-read, where sensitive data from...
