Piotr Bania of Cisco Talos is credited with the discovery of this vulnerability.
Cisco Talos, in conjunction with Apple’s security advisory issued on Mar 22, is disclosing the discovery of a local vulnerability in the communication functionality of the Apple Intel HD3000 Graphics kernel driver. This vulnerability was initially discovered by the Talos Vulnerability Research & Development Team and reported in accordance with responsible disclosure policies to Apple.
There is a local privilege escalation vulnerability in the Apple Intel HD3000 Graphics kernel driver (TALOS-2015-0088/CVE-2016-1743) which Talos has identified on OS X 10.11. Exploitation of this vulnerability requires user interaction, such as executing a malicious executable received via email or downloaded and run on the user’s Mac. With OS X becoming more common in the workplace this can be especially impactful as the common user accounts often do not have root-level permissions.
