What is CVE-2008-3528?
CVE-2008-3528 is a low-severity denial of service vulnerability in Linux kernel, published on 27 Sep 2008. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-264
