The vulnerability is locally exploitable and requires low privileges. No user interaction is required.

Q: What is the primary security impact?

The supplied severity vector indicates a high availability impact. It does not indicate confidentiality or integrity impact.

Q: Which Ubuntu kernel package families are in scope?

The affected software list includes ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, and their listed FIPS variants.

Published May 2, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: codel: remove sch->q.qlen check before qdisctreereducebacklog() After making all ->qlennotify() callbacks idempotent, now it is safe to remove the check of qlen!=0 from both fqcodeldequeue() and codelqdiscdequeue().
