wan: Missing capability checks in sbni_ioctl()
There are missing capability checks in the following code: 1300 static int 1301 sbni_ioctl( struct net_device *dev, struct ifreq *ifr, int cmd) 1302 { [...] 1319 case SIOCDEVRESINSTATS : 1320 if( current->euid != 0 ) /* root only */ 1321 return -EPERM; [...] 1336 case SIOCDEVSHWSTATE : 1337 if( current->euid != 0 ) /* root only */ 1338 return -EPERM; [...] 1357 case SIOCDEVENSLAVE : 1358 if( current->euid != 0 ) /* root only */ 1359 return -EPERM; [...] 1372 case SIOCDEVEMANSIPATE : 1373 if( current->euid != 0 ) /* root only */ 1374 return -EPERM; Here's my proposed fix: Missing capability checks.
