| Subject: CVE-2025-37842: spi: fsl-qspi: use devm function instead of driver remove |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| spi: fsl-qspi: use devm function instead of driver remove |
| |
| Driver use devm APIs to manage clk/irq/resources and register the spi |
| controller, but the legacy remove function will be called first during |
| device detach and trigger kernel panic. Drop the remove function and use |
| devm_add_action_or_reset() for driver cleanup to ensure the release |
| sequence. |
| |
| Trigger kernel panic on i.MX8MQ by |
| echo 30bb0000.spi >/sys/bus/platform/drivers/fsl-quadspi/unbind |
| |
| The Linux kernel CVE team has assigned CVE-2025-37842 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/439688dbe82baa10d4430dc3252bb5ef1183a171 |
