CVE-2025-0690

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...

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,...

CVE-2025-0685

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

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...

UBUNTU-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...

CVE-2024-45783

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...

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...

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 ...

CVE-2024-45779

An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a he...

CVE-2025-1118

A flaw was found in grub2. Grub's dump command is not blocked when grub is in lockdown mode, which allows the user to read any memory information, and an attacker may leverage this in order to extract signatures, salts, and other sensitive information from the memory...

CVE-2025-0686

A flaw was found in grub2. When performing a symlink lookup from a romfs filesystem, grub's romfs filesystem 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...

CVE-2024-45775

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...

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...

UBUNTU-CVE-2024-45775

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...

UBUNTU-CVE-2024-45778

A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash...

CVE-2025-1125

When reading data from a hfs filesystem, grub's hfs filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffers size, however it misses to properly check for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size...

PT-2025-7461

Name of the Vulnerable Software and Affected Versions grub2 affected versions not specified Description 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...

PT-2025-6796

Name of the Vulnerable Software and Affected Versions Grub2 affected versions not specified Description A flaw was found in command/gpg, where hooks created by loaded modules are not removed when the related module is unloaded. This allows an attacker to force Grub2 to call the hooks once the...

PT-2025-7467

Name of the Vulnerable Software and Affected Versions No specific software or versions mentioned. Description Integer overflow may lead to out-of-bounds write. Recommendations At the moment, there is no information about a newer version that contains a fix for this issue...
