Six U-Boot Flaws Enable Crash or Pre-Boot Code Execution

Engineer — Plan: Two of the six flaws allow pre-OS code execution if an attacker can supply a malicious boot image — relevant to anyone managing routers, smart cameras, or servers with BMC/management chips running U-Boot. No KEV or PoC yet, so plan to inventory U-Boot-dependent devices and track vendor firmware patches as they release.
SOC/IR — Learn: No IOCs, no active exploitation, and boot-level compromise is largely invisible to SIEM/EDR — nothing to hunt or detect today, but understanding pre-boot attack surfaces informs triage if a device integrity alert surfaces later.
Leader — Skip
