CVE-2026-43347
Description
A flaw was found in the Linux kernel. An issue with the system's firmware incorrectly identifying a section of memory reserved for the Gunyah hypervisor as available for general use can lead to the kernel attempting to access this protected area. This unauthorized memory access can cause the system to become unstable and crash, resulting in a Denial of Service (DoS).
