If amdgpu_dm_commit_zero_streams() or dm_dmub_hw_init() fails,\nthe function returns with the lock still held. The matching resume path\nis then skipped, so every later dc_lock take hangs.\n\nRelease the cached DC state and unlock before returning the error.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/295d2bf42061db490254e748f9344545bb7faf19","https://git.kernel.org/stable/c/92a9eebd2a1f892fe482154d83f9f1626bc73d3b","https://git.kernel.org/stable/c/dac29cbb405b912742f4f7eda833cec8e7a53780"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89820","score":0.00206,"percentile":0.10607,"date":"2026-10-25"},"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).
