# CVE-2025-62230: Xorg: xwayland: use-after-free in xkb client resource removal

Status: published. Published: 2025-10-30. Updated: 2026-11-05.

A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.

## Remediation

- workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. (source: CNA: redhat)
- fix: The reporting source identifies this reference as a patch. Check the advisory for affected versions and supported release branches. (source: af854a3a-2127-422b-91ae-364da2661108) — http://www.openwall.com/lists/oss-security/2025/10/28/7
