Registration failures can also\nleave an error pointer in priv->ptp.clock.\n\nCache the PHC index separately and report -1 while no clock is\nregistered. Normalize registration errors to NULL and preserve the\nstatic timestamping capabilities.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/0aaa53936419cf0c19c670387fc6d431e042a1b6","https://git.kernel.org/stable/c/1f77af0aaf277413ff32f6ff8c2c4282bd64c897","https://git.kernel.org/stable/c/29ffd972531f8e6e0edf4ea3496190acff9fc9c2","https://git.kernel.org/stable/c/8d4d06d6e2b501cb8e30ed3b1924c470358e8052","https://git.kernel.org/stable/c/bf3308416a2be85dcc9965b614a745b40beeff14"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-80992","score":0.00169,"percentile":0.06194,"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).
