So we need to check the rphy to avoid possible NULL pointer access.\n\nIf sas_rphy_add() returned with failure, rphy is set to NULL. We would\naccess the rphy in the following lines which would also result NULL pointer\naccess.","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/090305c36185c0547e4441d4c08f1cf096b32134","https://git.kernel.org/stable/c/6f0c2f70d9929208d8427ec72c3ed91e2251e289","https://git.kernel.org/stable/c/9937f784a608944107dcc2ba9a9c3333f8330b9e","https://git.kernel.org/stable/c/a26c775ccc4cfe46f9b718b51bd24313053c7e0b","https://git.kernel.org/stable/c/b5e5bbb3fa5f8412e96c5eda7f4a4af6241d6bd3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2023-53124","score":0.0019,"percentile":0.08668,"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).
