There is no remote or adjacent-network path into the block I/O scheduler.\nAC:L - The attacker fully controls every precondition \u2014 creating the BFQ queue merge chain with cooperating I/O threads, and forcing the blkcg serial-number change by migrating its own task between delegated cgroups or destroying a cgroup \u2014 and the free and subsequent use occur back-to-back inside the same bfqd-\u003elock critical section, so the UAF is deterministic rather than a race.\nPR:L - Only an unprivileged local account is needed: issuing I/O and moving a task within a delegated cgroup subtree or inside a container requires no capabilities, and the entire path from bfq_bio_merge() to bfq_sync_bfqq_move() contains no privilege check.\nUI:N - The attacking process performs the I/O and the cgroup migration itself; no action by another user or administrator is required.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - bic_set_bfqq() dereferences the freed bfq_queue and acts on its stale contents, and a use-after-free on a slab object that the attacker can groom yields an arbitrary-read primitive over reallocated kernel data.\nI:H - The code writes NULL into the freed 576-byte bfq_queue at a fixed offset (old_bfqq-\u003ebic = NULL), a genuine use-after-free write that corrupts whatever object subsequently occupies that slab slot, giving a controlled-offset write primitive leveragable for control-flow hijack.\nA:H - The use-after-free readily produces a kernel oops or panic \u2014 immediately under KASAN/KFENCE, and via corrupted bfq_queue/reallocated-object state otherwise \u2014 and can be re-triggered repeatedly by an unprivileged user."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
