| Description: | Race condition in the vop_ioctl function in drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver in the Linux kernel before 4.6.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (memory corruption and system crash) by changing a certain header, aka a "double fetch" vulnerability. Pengfei Wang discovered a race condition in the MIC VOP driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory.
