| Subject: CVE-2025-37746: perf/dwc_pcie: fix duplicate pci_dev devices |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| perf/dwc_pcie: fix duplicate pci_dev devices |
| |
| During platform_device_register, wrongly using struct device |
| pci_dev as platform_data caused a kmemdup copy of pci_dev. Worse |
| still, accessing the duplicated device leads to list corruption as its |
| mutex content (e.g., list, magic) remains the same as the original. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37746 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/a71c6fc87b2b9905dc2e38887fe4122287216be9 |
