kernel: packet: use consistent hard_header_len in non-ring send paths

A flaw was found in the Linux kernel's packet handling functions, specifically packetsnd and packetsendmsgspkt. This vulnerability arises from inconsistent handling of network device header lengths during packet construction. A local attacker could exploit this by triggering a race condition duri...

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...
