| Subject: CVE-2022-49617: ASoC: Intel: sof_sdw: handle errors on card registration |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: Intel: sof_sdw: handle errors on card registration |
| |
| If the card registration fails, typically because of deferred probes, |
| the device properties added for headset codecs are not removed, which |
| leads to kernel oopses in driver bind/unbind tests. |
| |
| We already clean-up the device properties when the card is removed, |
| this code can be moved as a helper and called upon card registration |
| errors. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49617 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/f2556ce6b35ae0fc72000a4daa21ded12665e2f2 |
