| Subject: CVE-2024-42093: net/dpaa2: Avoid explicit cpumask var allocation on stack |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net/dpaa2: Avoid explicit cpumask var allocation on stack |
| |
| For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask |
| variable on stack is not recommended since it can cause potential stack |
| overflow. |
| |
| Instead, kernel code should always use *cpumask_var API(s) to allocate |
| cpumask var in config-neutral way, leaving allocation strategy to |
| CONFIG_CPUMASK_OFFSTACK. |
| |
| Use *cpumask_var API(s) to address it. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42093 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: |
