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...
CVE-2025-0686
Affects grub2 ROMFS symlink handling (CVE-2025-0686). The romfs module uses user-controlled geometry parameters to size buffers in symlink lookups and fails to guard integer overflows, allowing buffer size miscalculation. This can cause grub_malloc to allocate too small a buffer, leading to out-o...

CVE-2025-0685
CVE-2025-0685 affects grub2, specifically the JFS filesystem module. The vulnerability arises from an integer overflow in buffer size calculations when reading data from JFS, allowing grub_jfs_read_file() to write beyond an internal buffer via grub_jfs_lookup_symlink(), which could corrupt grub’s...

CVE-2025-0678
The CVE-2025-0678 entry describes a grub2 squash4 filesystem flaw where integer overflow in buffer size calculations leads to grub_malloc() under-allocating and a heap-based out-of-bounds write during direct_read(), potentially allowing arbitrary code execution and bypass of secure boot. Connecte...
CVE-2024-45782
CVE-2024-45782 affects grub2, specifically the HFS filesystem path where grub_fs_mount() uses strcpy on a user-provided volume name, enabling a heap-based out-of-bounds write and potential secure-boot bypass. Affected packages include grub2 prior to the updated 2.06 releases; remediation is to up...
