The vulnerability of the implementations of grub_cmd_initrd and grub_initrd_init, the Grub2 operating system loaders, allows an attacker to access confidential data, compromise data integrity, and cause service failures.

The vulnerability of the implementations of grubcmdinitrd and grubinitrdinit, which are used by the Grub2 operating system loader, is related to the introduction of a large number of arguments into the initrd command in 32-bit architectures. Exploiting this vulnerability allows an attacker to gai...

The vulnerability in the implementation of the grub_script_function_create() function of the Grub2 operating system allows a perpetrator to gain access to confidential data, affect the integrity of the data, and cause service failures.

The vulnerability of the grubscriptfunctioncreate function, which is part of the Grub2 operating system loader, stems from an error in function overriding. This function is already being executed. Exploiting this vulnerability could allow a perpetrator to access confidential data, compromise data...

grub2: Integer overflow in grub_squash_read_symlink may lead to heap-based buffer overflow

A flaw was found in grub2. When handling squashfs filesystems containing a symbolic link with name length of UINT32 bytes in size, the name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data. The highes...
