https://notcve.org/view.php?id=CVE-2025-0686
03 Mar 2025 — 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 filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_romfs_read_symlink() may cause out-of-bounds... • https://access.redhat.com/security/cve/CVE-2025-0686 • CWE-787: Out-of-bounds Write •
