| Subject: CVE-2022-49251: ASoC: codecs: va-macro: fix accessing array out of bounds for enum type |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: codecs: va-macro: fix accessing array out of bounds for enum type |
| |
| Accessing enums using integer would result in array out of bounds access |
| on platforms like aarch64 where sizeof(long) is 8 compared to enum size |
| which is 4 bytes. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49251 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: |
