CVE-2026-97959

The Linux kernel contains a memory leak vulnerability in the net/sched: cls_route component. When an existing filter is moved to a different top-level bucket via route4_change, the filter is unlinked from the old bucket, but the bucket is never freed. This results in stale empty buckets remaining...
