It fails to verify that there is enough space remaining for the\nfixed 8-byte header of the structure.\n\nIf a server provides a DataOffset that leaves less than 8 bytes remaining,\nthe check passes, but subsequent reads of ReparseTag and ReparseDataLength\nwill occur out-of-bounds.\n\nFix this by ensuring the remaining space is at least the size of the\nreparse_data_buffer structure before accessing its fields.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3d67f155fe5813cfb02a551a9a12d6ea06a902e9","https://git.kernel.org/stable/c/5f0306e731e2f46e91419eae57eee3a241c055e0","https://git.kernel.org/stable/c/8dc5db3a0e583ea8d31d0613cefd99e93e095c3c","https://git.kernel.org/stable/c/aa00eead258e4fe8158a3a3e2d65facf06274abd","https://git.kernel.org/stable/c/d1152c96a3002e3df6b9a5b007cecaa7b19b4f79"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98168","score":0.00206,"percentile":0.10452,"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).
