- Summary
- CVE-2026-74559 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
xsk: drain continuation descs after overflow in xskbuildskb()
Fix generic xmit path multi-buffer logic when packets are either too big (count of descriptors exceed MAXSKBFRAGS) or an invalid descriptor is included in fragmented packet. Introduce xdpsock::draincont and act upon this flag - when it is set, keep on consuming descriptors from AF_XDP Tx ring and put them directly onto Cq. Previously these descriptors were silently lost and could never be reached again.
