CVE-2026-115221: Incorrect Authorization in Red Hat Red Hat Enterprise Linux 10
Description
CVE-2026-115221 is a medium severity vulnerability in FreeIPA on Red Hat Enterprise Linux 10. It involves an incorrect authorization check that allows an authenticated host to retrieve and revoke digital certificates assigned to other users or services. The flaw arises because ownership verification relies solely on matching the host name to the certificate's subject Common Name (CN), without confirming actual ownership in the directory service. This can enable an enrolled host to disrupt services by revoking certificates belonging to other entities.

Technical Analysis
This vulnerability in FreeIPA on Red Hat Enterprise Linux 10 is caused by improper authorization checks when handling digital certificates. Specifically, the system verifies ownership by matching the host name to the certificate's subject CN but does not confirm ownership in the directory service. As a result, an authenticated host can retrieve and revoke certificates assigned to other users or services, potentially disrupting those services.
Potential Impact
An authenticated host can revoke digital certificates belonging to other users or services, leading to potential service disruption. There is no confidentiality impact reported, but integrity and availability impacts are present due to unauthorized certificate revocation.
