In the Linux kernel, the following vulnerability has been resolved:
ACPI: GTDT: Don't corrupt interrupt mappings on watchdow probe failure
When failing the driver probe because of invalid firmware properties, the GTDT driver unmaps the interrupt that it mapped earlier.
However, it never checks whether the mapping of the interrupt actially succeeded. Even more, should the firmware report an illegal interrupt number that overlaps with the GIC SGI range, this can result in an IPI being unmapped, and subsequent fireworks (as reported by Dann Frazier).
Rework the driver to have a slightly saner behaviour and actually check whether the interrupt has been mapped before unmapping things.
