DIRTY COW LINUX KERNEL VULNERABILITY (CVE-2016-5195)
Last week a serious Local Privilege Escalation vulnerability was found in the Linux kernel, its called Dirty COW. The term COW stands for Copy-On-Write. A race condition was found on kernel's memory subsystem that handles the copy-on-write breakage of private read-only memory mappings. Thus an unprivileged local user can use this flaw to gain escalated access.
It affects all RHEL kernels used in 7.x, 6.x and 5.x.
