Vulnerability Details CVE-2026-43151
In the Linux kernel, the following vulnerability has been resolved:
Revert "media: iris: Add sanity check for stop streaming"
This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4.
Revert the check that skipped stop_streaming when the instance was in
IRIS_INST_ERROR, as it caused multiple regressions:
1. Buffers were not returned to vb2 when the instance was already in
error state, triggering warnings in the vb2 core because buffer
completion was skipped.
2. If a session failed early (e.g. unsupported configuration), the
instance transitioned to IRIS_INST_ERROR. When userspace attempted
to stop streaming for cleanup, stop_streaming was skipped due to the
added check, preventing proper teardown and leaving the firmware
in an inconsistent state.
