grub2: modules built in on EFI builds that allow loading arbitrary code, circumventing secure boot

It was discovered that grub2 builds for EFI systems contained modules that were not suitable to be loaded in a Secure Boot environment. An attacker could use this flaw to circumvent the Secure Boot mechanisms and load non-verified code. Attacks could use the boot menu if no password was set, or t...

The vulnerability of the Mac OS X operating system, which allows a hacker to trigger a service failure

The vulnerability of the EFI component in the Mac OS X operating system is related to errors in specifying the range of protected registers. Exploiting this vulnerability can allow a malicious actor to trigger a service failure through a specially crafted application...

kernel: execution in the early microcode loader

A stack-based buffer overflow flaw was found in the Linux kernel's early load microcode functionality. On a system with UEFI Secure Boot enabled, a local, privileged user could use this flaw to increase their privileges to the kernel ring0 level, bypassing intended restrictions in place...
