| Subject: CVE-2023-52697: ASoC: Intel: sof_sdw_rt_sdca_jack_common: ctx->headset_codec_dev = NULL |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52697 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/a410d58117d6da4b7d41f3c91365f191d006bc3d |
