CVE-2026-64227

In the Linux kernel, the following vulnerability has been resolved: ACPI: driver: Check ACPI_COMPANION() against NULL during probe Since every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override(), platform drivers that rely on the existence of a device's ACPI companion object should verify its presence. Accordingly, add requisite ACPI_COMPANION() or ACPI_HANDLE() checks against NULL to 13 platform drivers handling
