Bug Dirty Cow (CVE-2016-5195)

Why the kernel is not updated to fix the bug Dirty Cow (CVE-2016-5195)

http://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-5195.html

It is updated already.

Kernel 4.4.0-45 fixes the issue, as per the changelog (line 3-4):

http://changelogs.ubuntu.com/changelogs/pool/main/l/linux/linux_4.4.0-45.66/changelog

Check if you’re using the fixed kernel using the following command:

ov@Edge:~/Desktop$ cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-4.4.0-45-generic root=UUID=ba221910-241b-4d76-abe4-b2259cba54be ro

Edit:
Alternatively, go to MATE system monitor, in the “system” tab.

Thanks. He had understood that was solved with the Kernel 4.4.0-66. I have it updated.
