Linux kernel sysfs trigger memory misreference vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a memory misreference vulnerability that stems from a confusion in the instructions responsible for freeing memory when the sysfs trigger is removed. ...
