CVE-2026-90406: media: qcom: iris: handle runtime PM resume failure in core deinit
In the Linux kernel, the following vulnerability has been resolved:
media: qcom: iris: handle runtime PM resume failure in core deinit
Check the return value of pmruntimeresumeandget() in iriscoredeinit().
If runtime PM resume fails, skip hardware power-off operations but still perform software teardown and state transition. Also skip the corresponding pmruntimeputsync() call to avoid unbalanced runtime PM references.

In the Linux kernel qcom iris driver, update iris_core_deinit() to check the return value of pm_runtime_resume_and_get(); when runtime PM resume fails, skip hardware power-off operations and the corresponding pm_runtime_put_sync() call, while still performing software teardown and the state transition.
Event History
Frequently Asked Questions
If runtime PM resume fails during core teardown, is software cleanup still performed?
Yes. The fix keeps the software teardown and state transition even when the runtime PM resume attempt fails, while skipping hardware power-off operations.
What runtime PM reference handling is required after a failed resume attempt?
The corresponding pm_runtime_put_sync() call must be skipped. This avoids creating an unbalanced runtime PM reference.
