  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/exynos: vidi: use priv-\u003evidi_dev for ctx lookup in vidi_connection_ioctl()  vidi_connection_ioctl() retrieves the driver_data from drm_dev-\u003edev to obtain a struct vidi_context pointer. However, drm_dev-\u003edev is the exynos-drm master device, and the driver_data contained therein is not the vidi component device, but a completely different device.  This can lead to various bugs, ranging from null pointer dereferences and garbage value accesses to, in unlucky cases, out-of-bounds errors, use-after-free errors, and more.  To resolve this issue, we need to store/delete the vidi device pointer in exynos_drm_private-\u003evidi_dev during bind/unbind, and then read this exynos_drm_private-\u003evidi_dev within ioctl() to obtain the correct struct vidi_context pointer.",
