Senserva AI Opinion for CVE-2016-5195

This is the Linux kernel race condition in mm/gup.c widely known as Dirty COW, which lets any local user escalate privileges, and EPSS rates it at 84 percent exploit probability. It affected a huge span of kernel versions and remains a standard tool for turning a web shell into root. CISA KEV confirms active exploitation.

Do this: Scan Linux servers and appliances for pre-fix kernels, prioritizing internet-facing hosts and shared multi-user systems.
