If the buffer\nonly contains the base SMB2 header (64 bytes), accessing\nerr->ErrorContextCount (at offset 66) or err->ByteCount later in\nsymlink_data() will cause an out-of-bounds read.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":9.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/15dc0a4de743a1aaa7b859b3aea79f08c695396c","https://git.kernel.org/stable/c/2be11faf79e49fb8250a181ff0b4d2b2f084af83","https://git.kernel.org/stable/c/b8c8a704f0bc133deb171f6aeb6f3a684203e212","https://git.kernel.org/stable/c/b9561402489d41149f63e001a74384863b7b30a6","https://git.kernel.org/stable/c/d62b8d236fab503c6fec1d3e9a38bea71feaca20"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-46185","score":0.00525,"percentile":0.44234,"date":"2026-10-26"},"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).
