This simple fix is therefore\n  preferred for -stable backporting ]\n\nOn a system that implements FEAT_EPAN, read/write access to the idmap\nis denied because UXN is not set on the swapper PTEs. As a result,\nidmap_kpti_install_ng_mappings panics the kernel when accessing\n__idmap_kpti_flag. Fix it by setting UXN on these PTEs.\n\ud83d\udccf Published: 2025-06-18T11:04:07.956Z\n\ud83d\udccf Modified: 2025-06-18T11:04:07.956Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/775871d4be0d75e219cca937af843a4a1b60489a", "creation_timestamp": "2025-06-18T11:38:18.000000Z"}, {"uuid": "089cb122-5868-4191-8cee-d83dde541376", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2022-50232", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lrvfepnb6c2o", "content": "", "creation_timestamp": "2025-06-18T16:08:06.388129Z"}, {"uuid": "66881756-6798-4af4-9f3e-2b6c54ca7385", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "4f29edb9-4c4b-44ca-b041-9b050656b6ae", "vulnerability": "CVE-2022-50232", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"}]}
