{"id":"AZL-93885","summary":"CVE-2026-64511 affecting package kernel for versions less than 6.6.145.2-1","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":"2026-08-28T17:47:46.445496776Z","published":"2026-07-25T10:17:37Z","upstream":["CVE-2026-64511"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64511"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.145.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-93885.json"}}],"schema_version":"1.9.0"}
