Errors after allocation call ethosu_job_err_cleanup(), which frees\nthe job but leaks the uninitialized fence.\n\nA scheduler dependency error also lets ethosu_job_run() return before\ndma_fence_init(). Normal cleanup then passes a zeroed refcount to\ndma_fence_put().\n\nRelease done_fence in the common cleanup path and use\ndma_fence_was_initialized() to distinguish initialized fences from raw\nallocations.\n\n[robh: also fix goto]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2d2a3adc91950f9a18829dadc7317fb5180a15c5","https://git.kernel.org/stable/c/b3e0f79af1f27339d8d2527c02cc3e8397c2f69f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89976","score":0.00198,"percentile":0.09411,"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).
