Base vector

AV:L/AC:L/Au:N/C:C/I:N/A:N

Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.x

Description The issue allows attackers to obtain sensitive information from kernel stack memory. This can be achieved through a crafted MSM MCR IOCTL EVT GET ioctl call related to drivers/media/platform/msm/camera v1/mercury/msm mercury sync.c, or a crafted MSM JPEG IOCTL EVT GET ioctl call related to drivers/media/platform/msm/camera v2/jpeg 10/msm jpeg sync.c.

Recommendations For Linux kernel version 3.x, consider restricting access to the MSM MCR IOCTL EVT GET and MSM JPEG IOCTL EVT GET ioctl calls until a patch is available. As a temporary workaround, disabling the msm mercury sync.c and msm jpeg sync.c functions may help minimize the risk of exploitation.
