| Subject: CVE-2024-56785: MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a |
| |
| Fix the dtc warnings: |
| |
| arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider |
| arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider |
| arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' |
| |
| And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on |
| deprecated #address-cells/#size-cells handling"): |
| |
| WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106 of_bus_n_addr_cells+0x9c/0xe0 |
| Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0 |
| |
| The fix is similar to commit d89a415ff8d5 ("MIPS: Loongson64: DTS: Fix PCIe |
| port nodes for ls7a"), which has fixed the issue for ls2k (despite its |
| subject mentions ls7a). |
| |
| The Linux kernel CVE team has assigned CVE-2024-56785 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: |
| https://git.kernel.org/stable/c/5a2eaa3ad2b803c7ea442c6db7379466ee73c024 |
