Denial Of Service (DoS)

kernel is vulnerble to denial of service. A local user with the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory and causes the kernel to allocate memory that is not accounted for. With this vulnerability, continual reading of the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.
