| Subject: CVE-2025-37979: ASoC: qcom: Fix sc7280 lpass potential buffer overflow |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ASoC: qcom: Fix sc7280 lpass potential buffer overflow |
| |
| Case values introduced in commit |
| 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") |
| cause out of bounds access in arrays of sc7280 driver data (e.g. in case |
| of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()). |
| |
| Redefine LPASS_MAX_PORTS to consider the maximum possible port id for |
| q6dsp as sc7280 driver utilizes some of those values. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37979 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/d78888853eb53f47ae16cf3aa5d0444d0331b9f8 |
