| Subject: CVE-2025-37977: scsi: ufs: exynos: Disable iocc if dma-coherent property isn't set |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| scsi: ufs: exynos: Disable iocc if dma-coherent property isn't set |
| |
| If dma-coherent property isn't set then descriptors are non-cacheable |
| and the iocc shareability bits should be disabled. Without this UFS can |
| end up in an incompatible configuration and suffer from random cache |
| related stability issues. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37977 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: |
