Description

- In the Linux kernel, the following vulnerability has been resolved: xsk: drain continuation descs after
overflow in xsk_build_skb() Fix generic xmit path multi-buffer logic when packets are either too big
(count of descriptors exceed MAX_SKB_FRAGS) or an invalid descriptor is included in fragmented packet.
Introduce xdp_sock::drain_cont and act upon this flag - when it is set, keep on consuming descriptors from

never be reached again. (CVE-2026-74559)
