Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.4.33

Description The issue is related to the log prefix function in kernel/printk.c, which does not properly remove a prefix string from a syslog header. This allows local users to cause a denial of service, resulting in a buffer overflow and system crash, by leveraging /dev/kmsg write access and triggering a call console drivers function call.

Recommendations For Linux kernel versions prior to 3.4.33, update to version 3.4.33 or later to resolve the issue.
