CVE-2026-43151

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Revert "media: iris: Add sanity check for stop streaming"<br /> <br /> This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4.<br /> <br /> Revert the check that skipped stop_streaming when the instance was in<br /> IRIS_INST_ERROR, as it caused multiple regressions:<br /> <br /> 1. Buffers were not returned to vb2 when the instance was already in<br /> error state, triggering warnings in the vb2 core because buffer<br /> completion was skipped.<br /> <br /> 2. If a session failed early (e.g. unsupported configuration), the<br /> instance transitioned to IRIS_INST_ERROR. When userspace attempted<br /> to stop streaming for cleanup, stop_streaming was skipped due to the<br /> added check, preventing proper teardown and leaving the firmware<br /> in an inconsistent state.
