Refs: see the GHSA / vendor advisory / patched release linked on this page.
A vulnerability (unclassified) exists in linux-aws.
Check the vendor advisory for the affected versions of linux-aws.
Severity: ?. Risk of unauthorized operations or information disclosure.
Update to 5.4.0-1120.130~18.04.1.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'linux-aws' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Original description The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: adapt set backend to use GC transaction API Use the GC transaction API to replace the old and buggy gc API and the busy mark approach. No set elements are removed from async garbage collection anymore, instead the _DEAD bit is set on so the set element is not visible from lookup path anymore. Async GC enqueues transaction work that might be aborted and retried later. rbtree and pipapo set backends does not set on the _DEAD bit from the sync GC path since this runs in control plane path where mutex is held. In this case, set elements are deactivated, removed and then released via RCU callback, sync GC never fails.
