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...
