Nearly 200,000 Framework laptops and desktops shipped with a dangerous UEFI shell command that allows attackers to disable Secure Boot protections. The 'mm' memory modification tool—meant for diagnostics—can be exploited to load persistent bootkits like BlackLotus. Framework has released firmware patches for most models, but unpatched systems remain vulnerable to OS-level security bypasses.

Lenovo has rolled out urgent firmware updates to fix six high-severity vulnerabilities in its all-in-one desktops, allowing attackers to bypass Secure Boot protections and plant undetectable malware. Discovered by Binarly, these flaws stem from insecure customizations in the UEFI firmware, echoing similar supply chain weaknesses recently found in Gigabyte hardware. The patches highlight the escalating risks in firmware security, where exploits can persist even after OS reinstallation.

A perplexing case emerges where a Windows UEFI boot anomaly coincides with widespread authentication failures despite a KeePass database passing integrity checks. This incident highlights critical, often overlooked intersections between boot processes, cryptographic operations, and real-world security workflows.
