Scientific Linux Security Update : Important: kernel on SL6.x i386/x86_64 (Dirty COW)

High Nessus Plugin ID 94266


The remote Scientific Linux host is missing one or more security updates.


The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es) :

- A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
(CVE-2016-5195, Important)


Update the affected packages.
