Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： staging: media: ipu7: 修复 ipu7_resume() 中的 pm_runtime 引用计数泄漏问题 在 中，在恢复设备之前调用了 。 如果运行时电源管理（runtime PM）的恢复操作失败，引用计数仍然保持增加状态，而错误处理路径在返回时未减少该引用，从而导致引用计数泄漏。 应改用 ，该函数在失败时会自动平衡引用计数，从而避免泄漏。 错误时仍返回 0，因为恢复回调不应将失败状态传播给电源管理核心模块，这与 ipu6 驱动的行为保持一致。

Vulnerability Title
staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()
ipu7_resume() calls pm_runtime_get_sync() before resuming the device.
If the runtime PM resume fails, the usage count remains incremented, but
the error path returns without dropping the reference.
Use pm_runtime_resume_and_get() instead, which balances the usage count
on failure and avoids the leak. Keep returning 0 on error, as resume
callbacks should not propagate failures to the PM core, matching the
behaviour of the ipu6 driver.
