| Description | A flaw was found in xorg-x11-server. An authenticated local user can trigger an out-of-bounds heap memory read by sending specially crafted X Keyboard Extension (XKB) requests with inconsistent key range parameters. This flaw leads to information disclosure, allowing the user to read sensitive data from the server's heap memory. | A buffer overread in CheckKeySyms() in X.Org X Server before 21.1.25 and XWayland before 24.1.14 could be used by authenticated X clients to leak small amounts of information from X server memory or potentially crash the X server. |
