If smb2_parse_contexts() rejects malformed\ncontext data, SMB2_open() returns without closing the handle, leaving the\nserver-side handle open and num_remote_opens elevated.\n\nClose the handle after a post-CREATE context parsing failure so the error\npath releases the remote resource and balances the open count.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/566820af017e81497fb5e9d3ad6e7ffe2828bc8b","https://git.kernel.org/stable/c/80c67cc71d32ccafc89a29b669243b40d81b930f","https://git.kernel.org/stable/c/cdb36b09fb1f86d638d0afb44d621ed3f7c1d8eb","https://git.kernel.org/stable/c/eaa97a196a107d4ef8775df2248181624151812e","https://git.kernel.org/stable/c/f09875ff901e933e7b22c913daf51d21e9d93a45"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98453","score":0.00168,"percentile":0.06025,"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).
