| Subject: CVE-2025-37934: ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction |
| |
| Actually check if the passed pointers are valid, before writing to them. |
| This also fixes a USBAN warning: |
| UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25 |
| load of value 255 is not a valid value for type '_Bool' |
| |
| This is because playback_only is uninitialized and is not written to, as |
| the playback-only property is absent. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37934 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: |
