CVE-2015-7884
Published: 23 October 2015
The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel through 4.3.3 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a crafted application.
From the Ubuntu Security Team
It was discovered that the virtual video osd test driver in the Linux kernel did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel.
