Bluetooth radio proximity is required, matching the Adjacent classification.\nAC:L - The attacker controls both sides of the race: `SO_SNDTIMEO` sets `sk-\u003esk_sndtimeo`, which `sco_connect()` passes verbatim to `sco_sock_set_timer()`, so the timeout work can be scheduled to fire at an arbitrarily chosen moment and raced against `close()`, and `sco_sock_clear_timer()` uses non-sync `cancel_delayed_work()` so an in-flight work item is never waited for. syzbot produced a reproducer and confirmed the fix.\nPR:L - There is no `capable()` or `CAP_NET_*` check anywhere in `sco_sock_create/bind/listen/connect`, so any unprivileged local user can create SCO sockets and drive the connect/close sequence that frees the socket. Only basic local account access is needed, not root.\nUI:N - The whole sequence \u2014 socket creation, `SO_SNDTIMEO`, connect, close \u2014 is performed by the attacker\u0027s own process against a system Bluetooth adapter. No victim action is required.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - A use-after-free on `struct sock` lets the attacker respray the freed slab object and read back its contents through subsequent socket operations, giving a path to arbitrary kernel memory disclosure.\nI:H - The stale pointer is written through \u2014 `sock_hold()` performs an atomic increment on freed memory and `sk-\u003esk_err = ETIMEDOUT` writes into it \u2014 and `sk-\u003esk_state_change(sk)` performs an indirect call through a function pointer read from the freed object, providing a control-flow hijack primitive.\nA:H - Even without successful exploitation the UAF produces a KASAN splat / kernel oops or panic in `sco_sock_timeout()`, and it can be triggered repeatedly by an unprivileged process."

Detection rules are retrieved from Rulezet.

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.
