Linux Kernel 8250 Serial Driver Local Denial of Service Vulnerability

The Linux kernel is prone to a local denial-of-service vulnerability because the software fails to handle exceptional conditions.

A local attacker can exploit this issue to crash the affected computer, denying service to legitimate users. The attacker may also be able to execute arbitrary code, but this has not been confirmed.

This issue affects kernel versions 2.6 prior to 2.6.20.11.
