| Subject: CVE-2024-49963: mailbox: bcm2835: Fix timeout during suspend mode |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mailbox: bcm2835: Fix timeout during suspend mode |
| |
| During noirq suspend phase the Raspberry Pi power driver suffer of |
| firmware property timeouts. The reason is that the IRQ of the underlying |
| BCM2835 mailbox is disabled and rpi_firmware_property_list() will always |
| run into a timeout [1]. |
| |
| Since the VideoCore side isn't consider as a wakeup source, set the |
| IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled |
| during suspend-resume cycle. |
| |

| 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: |
