Astra Linux – Vulnerability in grub2

An integer overflow flaw was discovered in the BFS file system driver within grub2. When reading a file using an indirect extent map, grub2 fails to validate the number of extent entries to be read. A maliciously crafted or corrupted BFS file system may cause an integer overflow during file...

CVE-2025-68266

The CVE-2025-68266 entry concerns Linux kernel BFS filesystem handling when loading file types from disk. The root cause is that S_IFMT bits of inode->i_mode can become bogus if the 32-bit mode or attributes fields loaded from disk are corrupted. The Linux kernel documentation indicates BFS us...
