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 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_reiserfs_read_symlink() will call grub_reiserfs_read_real() with a overflown length parameter, leading to a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and can result in arbitrary code execution, by-passing secure boot protections.\n\ud83d\udccf Published: 2025-03-03T17:14:07.911Z\n\ud83d\udccf Modified: 2025-03-04T16:14:41.428Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/security/cve/CVE-2025-0684\n2. https://bugzilla.redhat.com/show_bug.cgi?id=2346119", "creation_timestamp": "2025-03-04T16:31:49.000000Z"}
