A program attached to\neither hook can therefore trigger the sock_owned_by_me() warning by\ncalling bpf_setsockopt() or bpf_getsockopt().\n\nDisallow bpf_setsockopt() and bpf_getsockopt() for CGROUP_UNIX_GETPEERNAME\nand CGROUP_UNIX_GETSOCKNAME.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/61769b9c882a964af3a6ebd9a8e43615f8713234","https://git.kernel.org/stable/c/84473a7e1813a2da7b759ab1d098a84998c8d3f5","https://git.kernel.org/stable/c/daeb74f5f398e847d1d42906aec6610406a34fdc","https://git.kernel.org/stable/c/fe91c3f64a738dd97e8542ad5bdfbe5ac430edf6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90159","score":0.002,"percentile":0.09757,"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).
