An out-of-bounds read flaw was found in the mix4 Linux kernel driver. Registering the last of a VLAN or MAC address with no free entries may cause an out-of-bounds read into the next page of memory, causing a panic if the page is not available. The command can only be executed by a local privileged user with CAP_NET_ADMIN or CAP_SYS_ADMIN capabilities. The largest threat from this vulnerabilty is availability to the system.
