CVE-2011-1079: Input Validation
First published: Tue Mar 01 2011(Updated: )
Description of problem: Struct ca is copied from userspace. It is not checked whether the "device" field is NULL terminated. This potentially leads to BUG() inside of alloc_netdev_mqs() and/or information leak by creating a device with a name made of contents of kernel stack.
