UBUNTU-CVE-2026-52988
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: join hook list via splice_list_rcu() in commit phase Publish new hooks in the list into the basechain/flowtable using splice_list_rcu() to ensure netlink dump list traversal via rcu is safe while concurrent ruleset update is going on.
