This means only cBPF programs need to be mitigated for BHB.\n\nIn addition, only mitigate cBPF programs that were loaded by an\nunprivileged user. Privileged users can also load the same program\nvia eBPF, making the mitigation pointless.","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":[],"references":["https://git.kernel.org/stable/c/038866e01ea5e5a3d948898ac216e531e7848669","https://git.kernel.org/stable/c/477481c4348268136227348984b6699d6370b685","https://git.kernel.org/stable/c/6e52d043f7dbf1839a24a3fab2b12b0d3839de7a","https://git.kernel.org/stable/c/80251f62028f1ab2e09be5ca3123f84e8b00389a","https://git.kernel.org/stable/c/df53d418709205450a02bb4d71cbfb4ff86f2c1e"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-37963","score":0.00202,"percentile":0.10145,"date":"2026-11-01"},"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).
