From the CVE entry: The error-reporting functionality in (1) fs/ext2/dir.c,
(2) fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel
2.6.26.5 does not limit the number of printk console messages that report
directory corruption, which allows physically proximate attackers to cause
a denial of service (temporary system hang) by mounting a filesystem that
has corrupted dir->i_size and dir->i_blocks values and performing (a) read
or (b) write operations. NOTE: there are limited scenarios in which this
crosses privilege boundaries.
