| Subject: CVE-2025-21711: net/rose: prevent integer overflows in rose_setsockopt() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net/rose: prevent integer overflows in rose_setsockopt() |
| |
| In case of possible unpredictably large arguments passed to |
| rose_setsockopt() and multiplied by extra values on top of that, |
| integer overflows may occur. |
| |
| Do the safest minimum and fix these issues by checking the |
| contents of 'opt' and returning -EINVAL if they are too large. Also, |
| switch to unsigned int and remove useless check for negative 'opt' |
| in ROSE_IDLE case. |
| |
| The Linux kernel CVE team has assigned CVE-2025-21711 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: |
