The fragmentation helpers queue\ntransmit fragments there while sending large initiator or target-mode\nframes, and those skbs remain owned by the driver until they are sent or\ndiscarded.\n\nIf the device is removed while fragments are still queued, the common\ncleanup path frees the PN533 state without releasing the queued fragment\nskbs, leaking them.\n\nPurge fragment_skb during cleanup alongside resp_q.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/130b5ad4492f8e53d0398ee3af2b0e2388504d11","https://git.kernel.org/stable/c/2f5d093194ec24d7c29b91bf7df014924e0f4ea1","https://git.kernel.org/stable/c/4a52ec2457ff8c26206fcc20fa1972cc35a678c4","https://git.kernel.org/stable/c/5718fc62198c38c2de5316020a90506f9e75e0bb","https://git.kernel.org/stable/c/9319c3c4962efc8697246b563ea31c6d47f085aa"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80797","score":0.00243,"percentile":0.15294,"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).
