OESA-2026-4575: libXtst security update

Q: What access does an attacker need to exploit this issue?

The vector is network-based and requires no privileges, but it does require user interaction. The available data does not specify what form that interaction takes.

Q: What is the likely impact if exploitation succeeds?

The reported impact is limited to availability: the CVSS vector indicates high availability impact, with no confidentiality or integrity impact.

Q: Which component should be checked for exposure?

Check systems using the openEuler libXtst package, which provides the X.Org X11 libXtst runtime library. The provided data does not identify affected or fixed package versions.
