| Subject: CVE-2024-50259: netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write() |
| |
| This was found by a static analyzer. |
| We should not forget the trailing zero after copy_from_user() |
| if we will further do some string operations, sscanf() in this |
| case. Adding a trailing zero will ensure that the function |
| performs properly. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50259 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: |
