| Subject: CVE-2024-27030: octeontx2-af: Use separate handlers for interrupts |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| octeontx2-af: Use separate handlers for interrupts |
| |
| For PF to AF interrupt vector and VF to AF vector same |
| interrupt handler is registered which is causing race condition. |
| When two interrupts are raised to two CPUs at same time |
| then two cores serve same event corrupting the data. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27030 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: |
