CVE-2011-1019

Published: 10 March 2011

The dev_load function in net/core/dev.c in the Linux kernel before 2.6.38 allows local users to bypass an intended CAP_SYS_MODULE capability requirement and load arbitrary modules by leveraging the CAP_NET_ADMIN capability.

From the Ubuntu security team

Vasiliy Kulikov discovered that the CAP_SYS_MODULE capability was not needed to load kernel modules. A local attacker with the CAP_NET_ADMIN capability could load existing kernel modules, possibly increasing the attack surface available on the system.
