| Subject: CVE-2024-26788: dmaengine: fsl-qdma: init irq after reg initialization |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| dmaengine: fsl-qdma: init irq after reg initialization |
| |
| Initialize the qDMA irqs after the registers are configured so that |
| interrupts that may have been pending from a primary kernel don't get |
| processed by the irq handler before it is ready to and cause panic with |
| the following trace: |

| 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: |
