RLSA-2026:93439: Important: libXi security update

Q: What must an attacker do to exploit these flaws?

The CVSS vector indicates network access is required, attack complexity is high, no privileges are required, and user interaction is required. The affected conditions involve oversized DEVICE_ENABLE replies and DEVICE_RESOLUTION messages.

Q: What is the potential impact if exploitation succeeds?

Both listed issues can lead to arbitrary code execution. The advisory rates confidentiality, integrity, and availability impact as high.

Q: Is a default configuration known to be affected?

The provided advisory does not state whether a default configuration is affected.
