Security Patch Release
Summary

Show ▼
Upstream fixes were accepted for six U-Boot flaws in the FIT signature verification code, advancing the security patch process for a bootloader component used during firmware startup. The issues include paths to arbitrary code execution and denial of service, which can undermine boot-time trust and enable stealthy firmware compromise. Downstream firmware updates are still needed before customers are protected, and some older unsupported devices may never receive a patch.
