Technical details
The vulnerability exists in the ELF file parsing logic of the Primary Bootloader, where insufficient validation of crafted ELF headers or sections can trigger memory corruption. An attacker with access to modify boot-time artifacts or through an adjacent network attack vector during device initialization could supply the malicious ELF file. Successful exploitation may result in arbitrary code execution in the bootloader context or device denial of service.
