This is not always the case\nas it's possible to encounter 'late' failures on the output of S1\ntranslation, e.g. a GFN outside of the memslots.\n\nFix it by preparing an external abort before returning from\nkvm_translate_vncr(). Get rid of the BUG_ON() in the fault injection\npath while at it.","published":"2026-08-28T06:49:08.085Z","modified":"2026-08-30T03:48:20.965158753Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.40"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4ead4def04659739c399bfcb063f8a906194c79f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/53804b6839573c9c6fff5f4cf075d6746267345e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f3e83345a56280efffe235c65593c7e544c0fcc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80665.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80665"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-30T03:48:20.965158753Z"}}
