UBUNTU-CVE-2025-21631: Use After Free

Q: Which Ubuntu kernel packages are identified as affected?

The affected Ubuntu kernel package families listed are linux-azure, linux-gcp, linux-gke, linux-gkeop, linux-riscv, linux-realtime, linux-hwe-edge, and linux-azure-fde.

Q: What access does an attacker need to exploit this issue?

The supplied severity vector indicates local access, low privileges, no user interaction, high attack complexity, and additional attack requirements. The impact is rated high for confidentiality, integrity, and availability within the vulnerable system.

Q: What component is involved in the use-after-free?

The flaw is in the Linux kernel block layer's BFQ I/O scheduler. The reported use-after-free involves waker_bfqq after bfq_split_bfqq(), with the fault observed during request initialization in bfq_init_rq().
