CVE-2026-43284

In the Linux kernel, the following vulnerability has been resolved: xfrm: esp: avoid in-place decrypt on shared skb frags MSGSPLICEPAGES can attach pages from a pipe directly to an skb. TCP marks such skbs with SKBFLSHAREDFRAG after skbsplicefromiter, so later paths that may modify packet data ca...

CVE-2026-43284

Summary of CVE-2026-43284 (Linux kernel): The issue occurs in ESP decryption for UDP paths when using shared skb frags. Specifically, after MSG_SPLICE_PAGES attaches pages to an skb, and SKBFL_SHARED_FRAG is set, ESP input could decrypt in place on data not privately owned by the skb, if the frag...
