CVE-2011-1019

[Paolo Pisati]

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.

Break-Fix: a8f80e8ff94ecba629542d9b4b5f5a8ee3eb565c 8909c9ad8ff03611c9c96c9a92656213e4bb495b
