{"id":"CVE-2026-64511","summary":"ACPI: NFIT: core: Fix possible NULL pointer dereference","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nACPI: NFIT: core: Fix possible NULL pointer dereference\n\nAfter commit 9b311b7313d6 (\"ACPI: NFIT: Install Notify() handler before\ngetting NFIT table\"), acpi_nfit_probe() installs an ACPI notify handler\nfor the NFIT device before checking the presence of the NFIT table.  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().","modified":"2026-07-27T04:03:22.729792338Z","published":"2026-07-25T08:52:03.818Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64511.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/027e128abb82788189d6d45b68e3e8e7329b67be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c8f73b0fbdf956c98e2329d5aaea3ad09a9cfb6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/452945662fd8e9862a2d2043239c7ee1815d1ac4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/873576e585da5d0fc5debbab74eed565c0acea99"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a44343fe230aa48c74ef09830f3c5c90848b257e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64511.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64511"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9b311b7313d6c104dd4a2d43ab54536dce07f960"},{"fixed":"a44343fe230aa48c74ef09830f3c5c90848b257e"},{"fixed":"3c8f73b0fbdf956c98e2329d5aaea3ad09a9cfb6"},{"fixed":"452945662fd8e9862a2d2043239c7ee1815d1ac4"},{"fixed":"873576e585da5d0fc5debbab74eed565c0acea99"},{"fixed":"027e128abb82788189d6d45b68e3e8e7329b67be"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64511.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.96"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64511.json"}}],"schema_version":"1.7.5"}
