Summary
CVE-2026-31416 affecting package kernel for versions less than 6.6.134.1-2
Details

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nfnetlink_log: account for netlink header size

This is a followup to an old bug fix: NLMSG_DONE needs to account for the netlink header size, not just the attribute size.

This can result in a WARN splat + drop of the netlink message, but other than this there are no ill effects.
