Description of problem: <a href="http://lkml.org/lkml/2010/9/11/170">http://lkml.org/lkml/2010/9/11/170</a> The CHELSIO_GET_QSET_NUM device ioctl allows unprivileged users to read 4 bytes of uninitialized stack memory, because the "addr" member of the ch_reg struct declared on the stack in cxgb_extension_ioctl() is not altered or zeroed before being copied back to the user. Acknowledgements: Red Hat would like to thank Dan Rosenberg for reporting this issue.
