CVE-2015-3288

Published: 16 October 2016

mm/memory.c in the Linux kernel before 4.1.4 mishandles anonymous pages, which allows local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero.

From the Ubuntu security team

Kirill A. Shutemov discovered that memory manager in the Linux kernel did not properly handle anonymous pages. A local attacker could use this to cause a denial of service or possibly gain administrative privileges.

Priority
