An oversized packet_len\ncan lead to an out-of-bounds read in skb_put_data().\n\nValidate packet_len to ensure it is non-zero and does not exceed\nBTINTEL_PCIE_BUFFER_SIZE - sizeof(*rfh_hdr), logging an error when\ninvalid.\n\nThis issue was reported by Claude Mythos. It can be simulated either by\nusing customized firmware configured to return an invalid packet_len or\nby modifying rfh_hdr->packet_len in the driver before calling\nbtintel_pcie_submit_rx_work().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/46884c0f92708f1d218fc94d88800227a19b52f8","https://git.kernel.org/stable/c/6436e1b5331b1aebf905c13e0880a37032719b75","https://git.kernel.org/stable/c/73a50c636425cb9f7ab647b5a97bd14dd5610076","https://git.kernel.org/stable/c/ab0159b1f7214ce9bad9862751e4553e635a21b1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97976","score":0.00168,"percentile":0.06049,"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).
