Description

The vulnerability allows a local user to perform service disruption.

The scm_send function in the scm layer for Linux kernel 2.4.x up to 2.4.28, and 2.6.x up to 2.6.9, allows local users to cause a denial of service (system hang) via crafted auxiliary messages that are passed to the sendmsg function, which causes a deadlock condition.
