grub2: cutmem command allows privileged user to remove memory regions when Secure Boot is enabled

A flaw was found in grub2. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this...

grub2: acpi command allows privileged user to load crafted ACPI tables when Secure Boot is enabled

A flaw was found in GRUB 2, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table SSDT containing code to overwrite the Linux kernel lockdown variable content direct...

grub2: Stack buffer overflow in grub_parser_split_cmdline()

A flaw was found in grub2. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with...

grub2: Out-of-bounds write in grub_usb_device_initialize()

A flaw was found in grub2. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the...
