In the Linux kernel, the following vulnerability has been resolved:

ACPI: processor: validate MADT IOAPIC entry bounds

The IOAPIC hotplug lookup parses both MADT and _MAT records directly.

The MADT walk previously used a subtable's declared length to advance

the cursor after only locating a generic header. The _MAT path likewise

passed a generic header to the IOAPIC helper.

Validate that a current record has a complete generic header, that its

declared length is contained in the available record range, and that a

typed IOAPIC record contains the full fixed IOAPIC body before reading

its fields. Use the same relation for both MADT and _MAT provider

paths. (NVD)
