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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/370e19042fb8ac68109f8bdb0fdd8118baf39318","https://git.kernel.org/stable/c/a58b9d1c1cf81c0b29f1983c63c3e0c0caa68398","https://git.kernel.org/stable/c/bd4f8fa216182f33c06d4c1e162975a0c42fb14e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43151","score":0.00126,"percentile":0.02269,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
