Ensure That the Password Protection Is Configured for GRUB

GRUB is the default bootloader of Linux. The bootloader can set the startup mode of the system. By setting the GRUB password, you can prevent attackers from modifying the GRUB setting to enter the single-user mode. If the GRUB password is not set, attackers can easily access the GRUB editing menu...

GNU GRUB Buffer Overflow Vulnerability

GNU GRUB is a Linux system boot program from the GNU community. GNU GRUB suffers from a buffer overflow vulnerability, which stems from an integer overflow problem contained in the read module, that can be exploited by an attacker to overwrite sensitive information, thereby bypassing secure boot...

OESA-2025-1452 grub2 security update

GNU GRUB is a Multiboot boot loader. It was derived from GRUB, the GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn. Security Fixes: grub2 allowed attackers with access to the grub shell to access files on the encrypted disks.CVE-2024-49504...

Medium: grub2

Issue Overview: A flaw was found in grub2. A specially crafted JPEG file can cause the JPEG parser of grub2 to incorrectly check the bounds of its internal buffers, resulting in an out-of-bounds write. The possibility of overwriting sensitive information to bypass secure boot protections is not...
