EPSS: 0.5% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2008-09-27 · updated 2026-06-16
Weakness: CWE-264

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.

Affected products

Linux kernel: 2.6.26.5
