| Subject: CVE-2024-35819: soc: fsl: qbman: Use raw spinlock for cgr_lock |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| soc: fsl: qbman: Use raw spinlock for cgr_lock |
| |
| smp_call_function always runs its callback in hard IRQ context, even on |
| PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock |
| for cgr_lock to ensure we aren't waiting on a sleeping task. |
| |
| Although this bug has existed for a while, it was not apparent until |
| commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change") |
| which invokes smp_call_function_single via qman_update_cgr_safe every |
| time a link goes up or down. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35819 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: |
