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-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-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...

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-2024-45783 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...

CVE-2024-45783 Grub2: fs/hfs+: refcount can be decremented twice

CVE-2024-45783

CVE-2024-45783 affects grub2, specifically the fs/hfs+ driver. The root cause is that when failing to mount an HFS+ grub, the hfsplus driver does not set an ERRNO value, which can lead to a NULL pointer access. Connected advisories confirm a fix is available in patched grub2 versions (e.g.,

CVE-2024-45781 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...

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. Mitigation Mitigation for this issue is either not available or the currently available options do not meet the Red Hat...

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...

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-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...
