# CVE-2025-62231: Xorg: xmayland: value overflow in xkbsetcompatmap()

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

A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.

## 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
