OESA-2025-1675 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: GNU GRUB aka GRUB2 through 2.12 does not use a constant-time algorithm for grubcryptomemcmp and thus allows side-chann...

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...

The vulnerability of GRUB, a software solution for monitoring the status of industrial systems like B&R APROL, allows an intruder to influence the confidentiality, integrity, and accessibility of protected information.

The vulnerability of GRUB, a software solution for monitoring the status of B&R APROL industrial systems, lies in the absence of authentication for a critical function. Exploiting this vulnerability could allow an intruder to influence the confidentiality, integrity, and accessibility of protecte...

CVE-2017-7622

dde-daemon, the daemon process of DDE Deepin Desktop Environment 15.0 through 15.3, runs with root privileges and hardly does anything to identify the user who calls the function through D-Bus. Anybody can change the grub config, even to append some arguments to make a backdoor or privilege...

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...

GNU GRUB Access Control Error Vulnerability

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...

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...

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: 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...

grub2: UFS: Integer overflow may lead to heap based out-of-bounds write when handling symlinks

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...

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: fs/hfs+: refcount can be decremented twice

A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access...
