Medium: grub2

Issue Overview: When reading the language .mo file in grubmofileopen, grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak...

OESA-2025-1291 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: A flaw was found in grub2 where the grubextcmddispatcher function calls grubarglistalloc to allocate memory for the...

GNU GRUB2 Buffer Overflow Vulnerability (CNVD-2025-08322)

GRUB2 is a multiple bootloader for the GNU Project. GNU GRUB2 suffers from a buffer overflow vulnerability that stems from a buffer overflow problem contained in reading the BFS file system. An attacker could exploit this vulnerability to cause a denial of service...
