A flaw was found in the X.Org X server. This vulnerability, an out-of-bounds read, affects the XKB (X Keyboard Extension) modifier map handling. An attacker with access to the X11 server can exploit this by sending a malformed request, which causes the server to read beyond its intended memory boundaries. This can lead to the exposure of sensitive information or cause the server to crash, resulting in a denial of service.
CVE-2026-34002 is an out-of-bounds read vulnerability in X.Org X server's XKB modifier map handling that allows attackers with X11 server access to trigger information disclosure or denial of service. The flaw can be exploited by sending malformed requests that cause the server to read beyond allocated memory boundaries.
