The\nremote pad may be NULL, if userspace tries to enable a stream that ends\nat an unconnected crossbar sink. When that occurs, the driver\ndereferences the NULL pad, leading to a crash.\n\nPrevent the crash by checking if the pad is NULL before using it, and\nreturn an error if it is.","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":["CWE-476"],"references":["https://git.kernel.org/stable/c/91c8ce42fcde09f1da24acab9013b3e19cb88a4e","https://git.kernel.org/stable/c/c4bd29bf5b7f67925bc1abd16069f22dadf5f061","https://git.kernel.org/stable/c/c95318607fbe8fdd44991a8dad2e44118e6b8812","https://git.kernel.org/stable/c/eb2f932100288dbb881eadfed02e1459c6b9504c","https://git.kernel.org/stable/c/91c8ce42fcde09f1da24acab9013b3e19cb88a4e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2023-52647","score":0.00222,"percentile":0.12788,"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).
