Since the vc4-drm gets removed before its dependent drivers\n(vc4_hvs/vc4_v3d) the vc4_hvs_unbind/vc4_v3d_unbind functions try to\nget drvdata of its master and fails with a null dereference error.\n\nUse the data pointer passed to the unbind functions directly instead of\ndev_get_drvdata(master). This avoids using potentially freed memory.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/261f0a3f0ac03248284f5116d3258f89c9642215","https://git.kernel.org/stable/c/3be8dcc1a5854cf24cc332e0d6fc865c47ff49a1","https://git.kernel.org/stable/c/708688ec31ac6b35103ba364dc300a09930079d4","https://git.kernel.org/stable/c/7dc3680b7ffe01add3e9299fde8471d2dd53a8ae","https://git.kernel.org/stable/c/8f62aae059e06746a18a00af27179c3c0f17f4c7"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-68303","score":0.00206,"percentile":0.10454,"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).
