This can lead to a use-after-free of the socket object.\n\nWhen nfc_llcp_recv_cc() moves the socket from the connecting_sockets\nlist to the sockets list, it does so without holding the socket lock.\nIf llcp_sock_release() is executing concurrently, it might have already\nunlinked the socket and dropped its references, which can result in\nnfc_llcp_recv_cc() linking a freed socket into the live list.\n\nFix this by holding lock_sock() during the state transition and list\nmovement in nfc_llcp_recv_cc().  After acquiring the lock, check if\nthe socket is still hashed to ensure it hasn't already been unlinked\nand marked for destruction by the release path.  This aligns the locking\npattern with recv_hdlc() and recv_disc().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-362","CWE-416"],"references":["https://git.kernel.org/stable/c/0b45c31746e1523d5d482fda8fcf54a35ac417f1","https://git.kernel.org/stable/c/650bdd8fdfab64a09ee474150313dbc48c374795","https://git.kernel.org/stable/c/ad8a27d63cac96bac441edd002209ebd996e12fb","https://git.kernel.org/stable/c/b2a60f7f846faaf5c2cdad4ea6d3a33e5f863183","https://git.kernel.org/stable/c/b493ea2765cc17cb8aa7e7544a4b6dcb05b6ed77"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-64010","score":0.00197,"percentile":0.0931,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
