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