CVE-2026-34000
xwayland: xorg: X.Org X server: Information disclosure and denial of service via out-of-bounds read in XKB geometry processing.
Severidad por fuente
La etiqueta propia de Trivy es CRITICAL. Crítica según NVD. Más baja según AlmaLinux (alta), Amazon (alta), Oracle (alta), Rocky Linux (alta), Red Hat (media).
Descripción
A flaw was found in the X.Org X server. This out-of-bounds read vulnerability in the XKB geometry processing, specifically within the `CheckSetGeom()` and `XkbAddGeomKeyAlias` functions, allows an attacker to read uninitialized or out-of-bounds memory. An attacker with a connection to the X11 server, either locally or remotely, can exploit this without user interaction. This could lead to the disclosure of memory contents or cause a denial of service by crashing the server.
