Note that, limit of 64 is\nchosen based on the current platform requirements. If requirement changes\nin the future, this limit can be increased.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/27d5e84e810b0849d08b9aec68e48570461ce313","https://git.kernel.org/stable/c/4665a29c08e1b36bc9db4814f9dde3d23e8fd1b0","https://git.kernel.org/stable/c/4c46413661431aa60fb134cd4ecdf8beaa39f824","https://git.kernel.org/stable/c/5cf6d5e5e3b804a44692fbf548a5179442e2e923","https://git.kernel.org/stable/c/8022876894d09ae485b499058c3357da683bcc5d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-46003","score":0.00129,"percentile":0.02474,"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).
