If\nthat table is not there, 0 is returned without allocating the acpi_desc\nobject and setting the driver data pointer of the NFIT device.  If the\nplatform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification\non the NFIT device at that point, acpi_nfit_uc_error_notify() will\ndereference a NULL pointer.\n\nPrevent that from occurring by adding an acpi_desc check against NULL\nto acpi_nfit_uc_error_notify().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/027e128abb82788189d6d45b68e3e8e7329b67be","https://git.kernel.org/stable/c/3c8f73b0fbdf956c98e2329d5aaea3ad09a9cfb6","https://git.kernel.org/stable/c/452945662fd8e9862a2d2043239c7ee1815d1ac4","https://git.kernel.org/stable/c/873576e585da5d0fc5debbab74eed565c0acea99","https://git.kernel.org/stable/c/a44343fe230aa48c74ef09830f3c5c90848b257e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-64511","score":0.00156,"percentile":0.0475,"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).
