Descriptions

drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux kernel before 4.5.3 allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a crafted number of planes in a VIDIOC_DQBUF ioctl call.

drivers/media/v4l2-core/videobuf2-v4l2.c en el kernel de Linux en versiones anteriores a 4.5.3 permite a usuarios locales provocar una denegación de servicio (operación de escritura en la memoria del kernel) o posiblemente tener otro impacto no especificado a través de un número manipulado de planos en una llamada VIDIOC_DQBUF ioctl.

Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the TTY implementation in the Linux kernel. A local attacker could use this to expose sensitive information. It was discovered that the Video For Linux Two implementation in the Linux kernel did not properly handle multiple planes when processing a VIDIOC_DQBUF ioctl. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
