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. The Linux kernel CVE team has assigned CVE-2026-43151 to this issue. Affected and fixed versions =========================== Issue introduced in 6.18.3 with commit f8b136296722e258ec43237a35f72c92a6d4501a and fixed in 6.18.16 with commit bd4f8fa216182f33c06d4c1e162975a0c42fb14e Issue introduced in 6.19 with commit ad699fa78b59241c9d71a8cafb51525f3dab04d4 and fixed in 6.19.6 with commit a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398 Issue introduced in 6.19 with commit ad699fa78b59241c9d71a8cafb51525f3dab04d4 and fixed in 7.0 with commit 370e19042fb8ac68109f8bdb0fdd8118baf39318 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions.

Affected files ============== The file(s) affected by this issue are: drivers/media/platform/qcom/iris/iris_vb2.c 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/bd4f8fa216182f33c06d4c1e162975a0c42fb14e https://git.kernel.org/stable/c/a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398 https://git.kernel.org/stable/c/370e19042fb8ac68109f8bdb0fdd8118baf39318
