| Description | A flaw was found in xorg-x11-server. A local authenticated client can exploit this flaw by sending a crafted input device ungrab request with an unvalidated modifier value. This lack of validation causes the server to perform an out-of-bounds write on the heap, resulting in memory corruption that can lead to a denial of service (DoS) or potential arbitrary code execution. | A heap buffer overflow caused by a XIPassiveUngrabDevice request with an out-of-range modifier value in X.Org X Server before 21.1.15 and XWayland before 24.1.14 could be used by authenticated X clients to crash or potentially execute code in X server context. |
