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.
