| Subject: CVE-2024-58077: ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback |
| |
| commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" |
| log severity") ignores -EINVAL error message on common soc_pcm_ret(). |
| It is used from many functions, ignoring -EINVAL is over-kill. |
| |
| The reason why -EINVAL was ignored was it really should only be used |
| upon invalid parameters coming from userspace and in that case we don't |
| want to log an error since we do not want to give userspace a way to do |
| a denial-of-service attack on the syslog / diskspace. |
| |
| So don't use soc_pcm_ret() on .prepare callback is better idea. |
| |
| The Linux kernel CVE team has assigned CVE-2024-58077 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: |
