| Subject: CVE-2022-49616: ASoC: rt7*-sdw: harden jack_detect_handler |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: rt7*-sdw: harden jack_detect_handler |
| |
| Realtek headset codec drivers typically check if the card is |
| instantiated before proceeding with the jack detection. |
| |
| The rt700, rt711 and rt711-sdca are however missing a check on the |
| card pointer, which can lead to NULL dereferences encountered in |
| driver bind/unbind tests. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49616 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/07a606e1389a63b61cb8cd591026f30529117573 |
