Linux kernel vc_resize denial of service

linux-vcresize-dos (18523) The risk level is classified as LowLow Risk

Description:

Linux kernel is vulnerable to an integer overflows in the vc_resize function in the vt.c file. A local attacker could exploit this vulnerability to cause the kernel to crash.
