CVE-2022-3675

Fedora CoreOS supports setting a GRUB bootloader password using a Butane config. When this feature is enabled, GRUB requires a password to access the GRUB command-line, modify kernel command-line arguments, or boot non-default OSTree deployments. Recent Fedora CoreOS releases have a...

SUSE-SU-2025:01615-1 Security update for grub2

This update for grub2 rebuilds the existing package with the new 4k RSA secure boot key for IBM Power and Z. Note: the signing key of x86 / x8664 and aarch64 architectures are unchanged. Also the following issue were fixed: - CVE-2025-4382: TPM auto-decryption data exposure bsc1242971 - Fix...

grub2: fs/ufs: OOB write in the heap

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...

grub2: commands/extcmd: Missing check for failed allocation

A flaw was found in grub2 where the grubextcmddispatcher function calls grubarglistalloc to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parseoption function, leading...

grub2: reader/jpeg: Heap OOB Write during JPEG parsing

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-2025-4382

A flaw was found in systems utilizing LUKS-encrypted disks with GRUB configured for TPM-based auto-decryption. When GRUB is set to automatically decrypt disks using keys stored in the TPM, it reads the decryption key into system memory. If an attacker with physical access can corrupt the underlyi...

GNU GRUB 访问控制错误漏洞

GNU GRUB is a Linux system boot program from the GNU community. An Access Control Error vulnerability exists in GNU GRUB, which stems from GRUB not clearing the key in memory during automatic TPM decryption, and can be exploited by an attacker to obtain unencrypted data...

The vulnerability of the UFS file system used by Grub2 for operating system installations allows a hacker to bypass the secure boot mechanism.

The vulnerability of the UFS file system used by Grub2 operating systems is related to writing beyond the buffer boundaries. Exploiting this vulnerability could allow an attacker to bypass the secure boot mechanism...

grub2: net: Out-of-bounds write in grub_net_search_config_file()

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...

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 ...

DEBIAN-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,...
