In particular, it allows the client to access any subdirectory or subtree of an exported directory, regardless of the set file permissions, and regardless of any 'root_squash' or 'all_squash' attributes that would normally be expected to apply to that client. ## Affected - `openshift_container_platform = 4.0` - `enterprise_linux = 6.0` - `enterprise_linux = 7.0` - `enterprise_linux = 8.0` - `enterprise_linux = 9.0` - `enterprise_linux = 10.0` - `nfs-utils` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Vendor advisories - **RHSA-2026:5873** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.16 · released 2026-04-02 · [advisory](https://access.redhat.com/errata/RHSA-2026:5873) - **RHSA-2026:5867** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.17 · released 2026-04-01 · [advisory](https://access.redhat.com/errata/RHSA-2026:5867) - **RHSA-2026:5127** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.18 · released 2026-03-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:5127) - **RHSA-2026:5877** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.19 · released 2026-04-01 · [advisory](https://access.redhat.com/errata/RHSA-2026:5877) - **RHSA-2026:3939** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10), Red Hat Enterprise Linux BaseOS (v. 10), Red Hat Enterprise Linux CodeReady Linux Builder (v. 10) · released 2026-03-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:3939) - **RHSA-2026:3942** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.4), Red Hat Enterprise Linux BaseOS EUS (v.9.4), Red Hat CodeReady Linux Builder EUS (v.9.4) · released 2026-03-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:3942) - **RHSA-2026:3941** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6), Red Hat Enterprise Linux BaseOS EUS (v.9.6), Red Hat CodeReady Linux Builder EUS (v.9.6) · released 2026-03-06 · [advisory](https://access.redhat.com/errata/RHSA-2026:3941) - **RHSA-2026:3940** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9), Red Hat Enterprise Linux BaseOS (v. 9), Red Hat Enterprise Linux CodeReady Linux Builder (v. 9) · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3940) - **RHSA-2026:3938** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS (v. 8), Red Hat Enterprise Linux CRB (v. 8) · released 2026-03-05 · [advisory](https://access.redhat.com/errata/RHSA-2026:3938) - **RHSA-2026:5606** · Red Hat · fixed in: Red Hat Ceph Storage 8 · released 2026-03-24 · [advisory](https://access.redhat.com/errata/RHSA-2026:5606) - **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 6, Red Hat OpenShift Container Platform 4, Red Hat Enterprise Linux 7 · updated 2026-10-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-12801.json)
