The vulnerability of the atmel_hlcdc_plane_atomic_duplicate_state() function in the driver/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c driver for the Direct Rendering Infrastructure (DRI) of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the atmelhlcdcplaneatomicduplicatestate function in the drivers/gpu/drm/atmel-hlcdc/atmelhlcdcplane.c driver of the Direct Rendering Infrastructure DRI infrastructure of the Linux operating system is related to the reutilization of previously freed memory. Exploiting this...
