Qualcomm Quic Mobile Station Modem Kernel

The CONFIG_STRICT_MEMORY_RWX implementation for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not properly consider certain memory sections, which makes it easier for attackers to bypass intended access restrictions by leveraging the presence of RWX memory at a fixed location.

Multiple stack-based buffer overflows 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, allow attackers to gain privileges via (1) a crafted VIDIOC_MSM_VPE_DEQUEUE_STREAM_BUFF_INFO ioctl call, related to drivers/media/platform/msm/camera_v2/pproc/vpe/msm_vpe.c, or (2) a crafted VIDIOC_MSM_CPP_DEQUEUE_STREAM_BUFF_INFO ioctl call, related to drivers/media/platform/msm/camera_v2/pproc/cpp/msm_cpp.c.

Multiple array index errors in drivers/media/video/msm/server/msm_cam_server.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, allow attackers to gain privileges by leveraging camera device-node access, related to the (1) msm_ctrl_cmd_done, (2) msm_ioctl_server, and (3) msm_server_send_ctrl functions.

goodix_tool.c in the Goodix gt915 touchscreen driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not properly synchronize updates to a global variable, which allows local users to bypass intended access restrictions or cause a denial of service (memory corruption) via crafted arguments to the procfs write handler.

goodix_tool.c in the Goodix gt915 touchscreen driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, relies on user-space length values for kernel-memory copies of procfs file content, which allows attackers to gain privileges or cause a denial of service (memory corruption) via an application that provides crafted values.

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 obtain sensitive information from kernel stack memory via (1) a crafted MSM_MCR_IOCTL_EVT_GET ioctl call, related to drivers/media/platform/msm/camera_v1/mercury/msm_mercury_sync.c, or (2) a crafted MSM_JPEG_IOCTL_EVT_GET ioctl call, related to drivers/media/platform/msm/camera_v2/jpeg_10/msm_jpeg_sync.c.
