UBUNTU-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...

UBUNTU-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...

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...

UBUNTU-CVE-2025-0684

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

UBUNTU-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...

UBUNTU-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...

GNU GRUB 安全漏洞

GRUB2 is a multiple bootloader for the GNU Project. GNU GRUB2 suffers from an out-of-bounds write vulnerability that stems from a flaw found in the HFS file system. No details of the vulnerability are provided at this time...

CVE-2024-57258

CVE-2024-57258 affects Das U-Boot (pre-2025.01-rc1) with integer overflows in memory allocation. Exploitation can occur via a crafted squashfs filesystem (via sbrk or request2size) or due to mishandling ptrdiff_t on x86_64, leading to memory corruption. Connected advisories corroborate the issue ...
