A malformed firmware response can return a different object\ntype or an empty buffer, and the direct ret->buffer.pointer dereference\ncan then access an invalid pointer.\n\nUse the typed _DSM helper, validate that the returned buffer contains at\nleast one byte, and free the ACPI object after reading it.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/08433c71f15984ddd5f5a307cf3f0aa9b84583aa","https://git.kernel.org/stable/c/3b597d24dc0455ae926f1053f97c2725038fc3cd","https://git.kernel.org/stable/c/7fea0c89ed39a13d9a31163a74f8c62de30a4ffc","https://git.kernel.org/stable/c/d5dfdf43259ad9d054052012095b1630e7366dcf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68346","score":0.00209,"percentile":0.1109,"date":"2026-10-31"},"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).
