AI Vulnerability Finding

Microsoft reports that its AI systems discovered multiple vulnerabilities in open-source bootloaders (GRUB2, U-Boot, Barebox), including integer and buffer overflows, filesystem parsing bugs, command flaws, and a cryptographic comparison side-channel; some issues could permit bypassing UEFI Secure Boot and arbitrary code execution under specific conditions, while several require physical access. The write-up emphasizes the significance of AI-driven discovery rather than evidence of active exploitation.
