| Doc Text: |
A heap buffer overflow issue was found in the load_device_tree() function of QEMU, which is invoked to load a device tree blob at boot time. It occurs due to device tree size manipulation before buffer allocation, which could overflow a signed int type. A user/process could use this flaw to potentially execute arbitrary code on a host system with privileges of the QEMU process.
