grub2: Fail kernel validation without shim protocol
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim...
grub2: Use-after-free redefining a function whilst the same function is already executing
GRUB2 contains a race condition in grubscriptfunctioncreate leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2...
grub2: Integer overflow in initrd size handling
Integer overflows were discovered in the functions grubcmdinitrd and grubinitrdinit in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu the functionality is not included in GRUB2 upstream, leading to a heap-based buffer overflow. These could be triggered by an extremely...
grub2: Crafted grub.cfg file can lead to arbitrary code execution during boot process
A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access...

USN-4440-1: linux kernel vulnerabilities
It was discovered that the network block device nbd implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service system crash. CVE-2019-16089 It was discovered that the kernel-user space relay...

grub2 data forgery issue vulnerability
grub2 is a Linux system bootloader from the GNU Project. A data forgery issue vulnerability exists in GRUB2 2.04 and earlier versions. The vulnerability stems from the program not verifying kernel signatures when booting directly without shim. An attacker could exploit this vulnerability to bypas...
CVE-2020-7205
A potential security vulnerability has been identified in HPE Intelligent Provisioning, Service Pack for ProLiant, and HPE Scripting ToolKit. The vulnerability could be locally exploited to allow arbitrary code execution during the boot process. Note: This vulnerability is related to using insmod...
