    CVE-2022-50230 – Linux Kernel Arm64 Uxn Inconsistent Page Table Vulnerability

    June 18, 2025

    CVE ID : CVE-2022-50230

    Published : June 18, 2025, 11:15 a.m. | 3 hours, 16 minutes ago

    Description : In the Linux kernel, the following vulnerability has been resolved:

    arm64: set UXN on swapper page tables

    [ This issue was fixed upstream by accident in c3cee924bd85 (“arm64:
    head: cover entire kernel image in initial ID map”) as part of a
    large refactoring of the arm64 boot flow. This simple fix is therefore
    preferred for -stable backporting ]

    On a system that implements FEAT_EPAN, read/write access to the idmap
    is denied because UXN is not set on the swapper PTEs. As a result,
    idmap_kpti_install_ng_mappings panics the kernel when accessing
    __idmap_kpti_flag. Fix it by setting UXN on these PTEs.

    Severity: 0.0 | NA
