CVE-2010-2963 EXPLOIT
6.2
MEDIUM · CVSS 2.0 · EPSS 0.8% (pctl 56)
Patch early
A public exploit exists.
Description
drivers/media/video/v4l2-compat-ioctl32.c in the Video4Linux (V4L) implementation in the Linux kernel before 2.6.36 on 64-bit platforms does not validate the destination of a memory copy operation, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via a VIDIOCSTUNER ioctl call on a /dev/video device, followed by a VIDIOCSMICROCODE ioctl call on this device.
