The following security vulnerabilities have been identified in the camera driver.
The camera driver provides an ioctl system call interface to user space clients for communication. When processing this communication, the msm_ioctl_server, msm_server_send_ctrl, and msm_ctrl_cmd_done functions use a user-supplied value as an index to the server_queue array for read and write operations without any boundary checks. A local application with access to the camera device nodes can use this flaw to, e.g., elevate privileges.
