      "title": "platform/surface: acpi-notify: Check ACPI companion before use",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/surface: acpi-notify: Check ACPI companion before use\n\nSince every platform driver can be forced to match a device that doesn't\nmatch its list of device IDs because of device_match_driver_override(),\nplatform drivers that rely on the existence of a device's ACPI companion\nobject should verify its presence.\n\nsan_probe() dereferences the result of ACPI_COMPANION() when installing\nthe GSBUS address space handler, so force-binding the driver to a device\nwithout an ACPI companion leads to a NULL pointer dereference.  The\ndereference was introduced when the probe function was switched from\nACPI_HANDLE() to ACPI_COMPANION().\n\nCheck the ACPI companion against NULL and return -ENODEV when it is\nmissing, like commit e4865a56d013 (\"ACPI: driver: Check ACPI_COMPANION()\nagainst NULL during probe\") does for the core ACPI platform drivers.",
