      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/atmel-hlcdc: fix use-after-free of drm_crtc_commit after release\n\nThe atmel_hlcdc_plane_atomic_duplicate_state() callback was copying\nthe atmel_hlcdc_plane state structure without properly duplicating the\ndrm_plane_state. In particular, state->commit remained set to the old\nstate commit, which can lead to a use-after-free in the next\ndrm_atomic_commit() call.\n\nFix this by calling\n__drm_atomic_helper_duplicate_plane_state(), which correctly clones\nthe base drm_plane_state (including the ->commit pointer).\n\nIt has been seen when closing and re-opening the device node while\nanother DRM client (e.g. fbdev) is still attached:\n\n=============================================================================\nBUG kmalloc-64 (Not tainted): Poison overwritten\n-----------------------------------------------------------------------------\n\n0xc611b344-0xc611b344 @offset=836.
