CVE-2024-45780

A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap...

DEBIAN-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-2025-0689

CVE-2025-0689 affects grub2, specifically the udf filesystem reader (grub_udf_read_block), where user-controlled data length metadata can cause a heap-based buffer overflow during disk read and sector iteration. This could corrupt data and allow arbitrary code execution, potentially bypassing sec...

CVE-2025-1125

CVE-2025-1125 concerns grub2, specifically the hfs filesystem module (fs/hfs) where integer overflow in buffer size calculations enables a heap-based out-of-bounds write. This can corrupt grub’s internal data and may allow arbitrary code execution with secure-boot bypass. Affected product: grub2 ...
