{"apiVersion":"1.0","identifier":"CVE-2026-99273","description":"In the Linux kernel, the following vulnerability has been resolved: ksmbd: reserve space for the UTF-16 terminator in stream info smb_strtoUTF16() always writes a terminating zero UTF-16 unit after the converted characters, but get_file_stream_info() budgets only sizeof(struct smb2_file_stream_info) + streamlen * 2 for a stream entry and sizeof(struct smb2_file_stream_info) + 7 * 2 for the trailing -::$DATA- entry. When an entry exactly fills the 448-byte small response buffer, the terminator is written two bytes past the allocation. Reserve one extra UTF-16 unit in both budget checks. The terminator is not part of the wire format, so the reported lengths are unchanged.","publishedAt":"2026-11-07T14:17:02","lastModifiedAt":"2026-11-10T19:22:31","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99273","cvssScore":null,"cvssVector":null,"epssProbability":0.00157,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99273","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99273","en":"https://www.redsauce.net/en/cves/CVE-2026-99273","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99273","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99273","de":"https://www.redsauce.net/de/cves/CVE-2026-99273","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99273","el":"https://www.redsauce.net/el/cves/CVE-2026-99273"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99273"}}
