CVE-2023-52697

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: ASoC: Intel: sof_sdw_rt_sdca_jack_common: ctx->headset_codec_dev = NULL sof_sdw_rt_sdca_jack_exit() son usados por diferentes códecs, y algunos de ellos usan el mismo nombre dai. Por ejemplo, rt712 y rt713 usan "rt712-sdca-aif1" y sof_sdw_rt_sdca_jack_exit(). Como resultado, mc_dailink_exit_loop() llamará dos veces a sof_sdw_rt_sdca_jack_exit(). Establecer ctx->headset_codec_dev = NULL; después de put_device(ctx->headset_codec_dev); para evitar que ctx->headset_codec_dev se coloque dos veces.

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: sof_sdw_rt_sdca_jack_common: ctx->headset_codec_dev = NULL sof_sdw_rt_sdca_jack_exit() are used by different codecs, and some of them use the same dai name. For example, rt712 and rt713 both use "rt712-sdca-aif1" and sof_sdw_rt_sdca_jack_exit(). As a result, sof_sdw_rt_sdca_jack_exit() will be called twice by mc_dailink_exit_loop(). Set ctx->headset_codec_dev = NULL; after put_device(ctx->headset_codec_dev); to avoid ctx->headset_codec_dev being put twice.

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service.
