Passing the payload byte count can make it read beyond\nthe descriptor buffer.\n\nValidate that the payload has an even byte count, pass a code-unit count to\nthe converter, and allocate sufficient UTF-8 output space.\n\nThe raw string buffer starts after the descriptor header but its size is\nbLength. Copying bLength bytes from that pointer can read beyond the\nresponse buffer.\n\nAllocate a zeroed bLength-sized buffer and copy only the UTF-16\npayload. This preserves the raw buffer size consumed by the RPMB device-ID\nABI while avoiding the overread.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/02dd1a65dff842d9360a38ebe243dc8f6adbbaf5","https://git.kernel.org/stable/c/566109f1ee4e389b4effab43b0ce1fdab302e9de","https://git.kernel.org/stable/c/66da25277256b6bf4c3fdbf3c9bfd43324c9cf25","https://git.kernel.org/stable/c/d96e83d028d7d8762e424e49c671d49ac2ecf14f","https://git.kernel.org/stable/c/f3480c59f4ce97d831e9d06f5a2b9c20547ed1a4"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-92480","score":0.00209,"percentile":0.10921,"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).
