A component can therefore have comp->cfg allocated while some\nRISes still have ris->mbwu_state set to NULL.\n\nPassing a NULL mbwu_state to add_to_garbage() dereferences the NULL\npointer inside the macro.\n\nSkip RISes that do not have an mbwu_state object before adding them to\nthe garbage list.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/977f52909c624210178a1247fab0b02b110c1106","https://git.kernel.org/stable/c/ca1f96334267ab8d47b2c9d535cdc9920fdde269"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68345","score":0.00198,"percentile":0.09612,"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).
