| Subject: CVE-2024-38541: of: module: add buffer overflow check in of_modalias() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| of: module: add buffer overflow check in of_modalias() |
| |
| In of_modalias(), if the buffer happens to be too small even for the 1st |
| snprintf() call, the len parameter will become negative and str parameter |
| (if not NULL initially) will point beyond the buffer's end. Add the buffer |
| overflow check after the 1st snprintf() call and fix such check after the |
| strlen() call (accounting for the terminating NUL char). |
| |
| The Linux kernel CVE team has assigned CVE-2024-38541 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: |
