Upgrade Amazon-Linux:2023 kernel-tools-devel to version 1:6.1.188-233.385.amzn2023 or higher.
This issue was patched in ALAS2023-2026-3197.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools-devel package and not the kernel-tools-devel package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.
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.
