Add required sanity checking to minix_check_superblock() The minix filesystem driver does not validate several superblock fields before using them during mount, allowing a crafted filesystem image to trigger out-of-bounds accesses (reported by syzbot). Consolidate and strengthen superblock validation in minix_check_superblock(). /* Testing */ gcc (Debian 14.2.0-19) 14.2.0 Debian clang version 19.1.7 (3+b1) No build failures or warnings were observed. /* Conflicts */ Merge conflicts with mainline ============================= No known conflicts.
