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: 2025-06-18T11:04:06.716Z\n\ud83d\udccf Modified: 2025-06-18T11:04:06.716Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/9283e708a9b8529e7aafac9ab5c5c79a9fab8846", "creation_timestamp": "2025-06-18T11:38:20.000000Z"}]}
