| Subject: CVE-2024-36978: net: sched: sch_multiq: fix possible OOB write in multiq_tune() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: sched: sch_multiq: fix possible OOB write in multiq_tune() |
| |
| q->bands will be assigned to qopt->bands to execute subsequent code logic |
| after kmalloc. So the old q->bands should not be used in kmalloc. |
| Otherwise, an out-of-bounds write will occur. |
| |
| The Linux kernel CVE team has assigned CVE-2024-36978 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: |
