CVE-2025-0689 Grub2: udf: heap based buffer overflow in grub_udf_read_block() may lead to arbitrary code execution

When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size whi...

CVE-2025-1125 Grub2: fs/hfs: integer overflow may lead to heap based out-of-bounds write

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...

CVE-2025-0690 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...

SUSE CVE-2024-45774

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...

SUSE 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...
