No capability, namespace privilege, or NFC hardware is needed to reach the vulnerable copy.\nUI:N - A single attacker-issued syscall sequence reaches the flaw; no administrator or other user has to open, mount, or configure anything.\nS:U - The out-of-bounds read stays within the kernel\u0027s own memory and the affected NFC socket state, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a kernel slab out-of-bounds read (KASAN-confirmed) of adjacent heap contents, and the disclosed value is partially exfiltrable to userspace: bytes past the buffer land in `opt`, gate control flow via the `LLCP_MAX_RW`/`LLCP_MAX_MIUX` checks, and are stored into `llcp_sock-\u003erw`/`miux` where `nfc_llcp_getsockopt()` returns them, giving a repeatable heap-content oracle.\nI:N - The defect is purely a read; nothing is written outside any object, and the only values stored (`llcp_sock-\u003erw`, `llcp_sock-\u003emiux`) remain inside their validated ranges and are settable legitimately by the same user anyway.\nA:H - The read walks off the end of a small `kmalloc()` buffer, which on KASAN/SLUB_DEBUG/`panic_on_warn` or MTE-hardened kernels (e.g. Android) produces a fatal report rather than a recoverable error, and the syscall can be repeated at will 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.
