CVE-2025-0690

GRUB2 contains a heap-based out-of-bounds write triggered by an integer overflow in the read module, allowing corruption of GRUB internals and potential secure-boot bypass. Affected: GRUB2; root cause: read path overflow in buffering logic; impact as stated is high for confidentiality/integrity/a...

CVE-2025-0690 Grub2: read: integer overflow may lead to out-of-bounds write

The read command is used to read the keyboard input from the user, while reads it keeps the input length in a 32-bit integer value which is further used to reallocate the line buffer to accept the next character. During this process, with a line big enough it's possible to make this variable to...

SUSE CVE-2024-45774

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 discarded...

SUSE CVE-2024-45776

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 sensitive data o...

SUSE CVE-2024-45777

A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grubgettextgetstrfromposition may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the...

SUSE CVE-2024-45780

A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap...

SUSE CVE-2024-45781

A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure...

SUSE CVE-2024-45782

A flaw was found in the HFS filesystem. When reading an HFS volume's name at grubfsmount, the HFS filesystem driver performs a strcpy using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer,...

SUSE CVE-2025-0624

A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grubstrcpy function. During this step, it fails to consider the environment variable length...

SUSE CVE-2025-0677

A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grubmalloc may be called with a smaller...

SUSE CVE-2025-0678

A flaw was found in grub2. When reading data from a squash4 filesystem, grub's squash4 fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some ...
