Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> minix: Add required sanity checking to minix_check_superblock()<br /> <br /> The fs/minix implementation of the minix filesystem does not currently<br /> support any other value for s_log_zone_size than 0. This is also the<br /> only value supported in util-linux; see mkfs.minix.c line 511. In<br /> addition, this patch adds some sanity checking for the other minix<br /> superblock fields, and moves the minix_blocks_needed() checks for the<br /> zmap and imap also to minix_check_super_block().<br /> <br /> This also closes a related syzbot bug report.
