| Subject: CVE-2024-42113: net: txgbe: initialize num_q_vectors for MSI/INTx interrupts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: txgbe: initialize num_q_vectors for MSI/INTx interrupts |
| |
| When using MSI/INTx interrupts, wx->num_q_vectors is uninitialized. |
| Thus there will be kernel panic in wx_alloc_q_vectors() to allocate |
| queue vectors. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42113 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: |
| https://git.kernel.org/stable/c/9edc7a83cd40ac96ff14fe3a17a38f7ace6611df |
