| Subject: CVE-2024-35806: soc: fsl: qbman: Always disable interrupts when taking cgr_lock |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| soc: fsl: qbman: Always disable interrupts when taking cgr_lock |
| |
| smp_call_function_single disables IRQs when executing the callback. To |
| prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. |
| This is already done by qman_update_cgr and qman_delete_cgr; fix the |
| other lockers. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35806 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: |
