Buffers were not returned to vb2 when the instance was already in\n   error state, triggering warnings in the vb2 core because buffer\n   completion was skipped.\n\n2. If a session failed early (e.g. unsupported configuration), the\n   instance transitioned to IRIS_INST_ERROR. When userspace attempted\n   to stop streaming for cleanup, stop_streaming was skipped due to the\n   added check, preventing proper teardown and leaving the firmware\n   in an inconsistent state."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/media/platform/qcom/iris/iris_vb2.c"],"versions":[{"version":"f8b136296722e258ec43237a35f72c92a6d4501a","lessThan":"bd4f8fa216182f33c06d4c1e162975a0c42fb14e","status":"affected","versionType":"git"},{"version":"ad699fa78b59241c9d71a8cafb51525f3dab04d4","lessThan":"a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398","status":"affected","versionType":"git"},{"version":"ad699fa78b59241c9d71a8cafb51525f3dab04d4","lessThan":"370e19042fb8ac68109f8bdb0fdd8118baf39318","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/media/platform/qcom/iris/iris_vb2.c"],"versions":[{"version":"6.19","status":"affected"},{"version":"0","lessThan":"6.19","status":"unaffected","versionType":"semver"},{"version":"6.18.16","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.6","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18.3","versionEndExcluding":"6.18.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"6.19.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bd4f8fa216182f33c06d4c1e162975a0c42fb14e"},{"url":"https://git.kernel.org/stable/c/a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398"},{"url":"https://git.kernel.org/stable/c/370e19042fb8ac68109f8bdb0fdd8118baf39318"}],"title":"Revert \"media: iris: Add sanity check for stop streaming\"","x_generator":{"engine":"bippy-1.2.0"}}}}
