CVE-2015-0568

Use-after-free vulnerability in the msm_set_crop function in drivers/media/video/msm/msm_camera.c in the MSM-Camera driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges or cause a denial of service (memory corruption) via an application that makes a crafted ioctl call.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
