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.","published":"2025-05-20T16:15:35.000Z","lastModified":"2026-06-17T09:15:47.000Z","status":"Analyzed","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["linux/linux kernel","debian/debian linux"],"epss":{"score":0.00204,"percentile":0.10236,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.20%).
