Vulnerabilities 8
-
Medium 6.7
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 boo…

Grub2: grub-core/gettext: integer overflow leads to heap oob write and read.
When reading the language .mo file in grub_mofile_open(), 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 a…

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 allo…
-
Medium 6.4
Grub2: command/gpg: use-after-free due to hooks not being removed on module unload
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to …

Medium 6.4
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, grub…
-
Medium 6.1CVE-2025-0690 Public exploit
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…
-
Medium 5.2
Grub2: commands/extcmd: missing check for failed allocation
A flaw was found in grub2 where the grub_extcmd_dispatcher() function calls grub_arg_list_alloc() 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 …
-
Medium 4.4
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.
