In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hard_header_len in TX_RING send path tpacket_snd() reads… (CVE-2026-74668)CVE-2026-74668 0 A vulnerability in the Linux kernel's packet TX_RING send path was resolved by ensuring consistent use of the hard_header_len value during frame processing. The issue involved tpacket_snd() reading dev->hard_header_len independently in different stages, which could lead to inconsistencies in reserved headroom and copy length calculations during concurrent network device reconfiguration. This could cause memory handling errors in packet processing. The fix snapshots the hard_header_len once before processing frames and uses this consistent value throughout the operation.
