| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| dyndbg: fix old BUG_ON in >control parser |

| Fix a BUG_ON from 2009. Even if it looks "unreachable" (I didn't |
| really look), lets make sure by removing it, doing pr_err and return |
| -EINVAL instead. |

| 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: |
