CVE-2026-93515

A use-after-free in present_clear_window_notifies() in the X.org X Server before 21.1.25 and X Wayland before 24.1.14 could be used by malicious X clients to crash or potentially execute code in the X server context.

X.Org X11 X server

Security Fix(es):

A flaw was found in the X.Org X Server and XWayland. An error handling issue in the X Keyboard Extension (XKB) geometry processing fails to clear a memory pointer after an allocation failure, leading to a double-free condition during cleanup. A local user can exploit this vulnerability by sending a specially crafted request to the display server. This can cause memory corruption, potentially resulting in a Denial of Service (DoS) or arbitrary code execution with elevated privileges. (From Red Hat.)(CVE-2026-88812)

A flaw was found in xorg-x11-server. A use-after-free vulnerability, where the application accesses memory after it has already been released, occurs in the Present extension because window notification entries are not properly unlinked before cleaning up window resources. An authenticated local X client can exploit this flaw by creating cross-window notifications and subsequently destroying the target window. Successful exploitation primarily results in a Denial of Service (DoS) via an X server crash, and may potentially lead to information disclosure.(CVE-2026-93515)

A flaw was found in xorg-x11-server. A local user can exploit a use-after-free condition—where the software attempts to access memory after it has been freed—by establishing a passive input grab and removing an input device. When subsequent input events are processed, the server dereferences the dangling device pointer. This flaw can lead to arbitrary code execution or a Denial of Service (DoS) via an X server crash.(CVE-2026-93516)

A flaw was found in xorg-x11-server. The GLX (OpenGL Extension to the X Window System) interface fails to verify that incoming data sizes do not exceed allocated buffer limits when handling large rendering requests. An authenticated local client can exploit this vulnerability by sending a specially crafted request, triggering a heap-based buffer overflow. Successful exploitation can result in arbitrary code execution with the privileges of the X server or cause a Denial of Service (DoS) by crashing the application. (From Red Hat.)(CVE-2026-93517)

A flaw was found in xorg-x11-server. Due to an integer truncation issue during memory allocation calculations within the X Keyboard Extension (XKB), the server allocates an undersized buffer when resizing key types. An authenticated local client can exploit this vulnerability by sending specially crafted XKB requests, causing a heap-based buffer overflow. This can result in arbitrary code execution or a denial of service (DoS). (From Red Hat.)(CVE-2026-93518)

Input_constrain_cursor() writes barrier events into a fixed-size buffer without checking bounds. When more than 100 pointer barriers are active, the writes overflow the fixed buffer on the stack or heap. An authenticated X client can trigger this by creating more than 100 pointer barriers (using the XFIXES extension) and then generating pointer motion events (e.g. via XTEST). Both extensions are enabled by default.(CVE-2026-93519)

A flaw was found in xorg-x11-server. In the X Keyboard Extension (XKB), key name memory is allocated with an insufficient buffer size compared to the maximum supported range. An authenticated local client can exploit this flaw by sending requests that modify the keycode range, triggering a heap-based buffer overflow. This vulnerability can lead to arbitrary code execution or cause a Denial of Service (DoS) by crashing the X server.(CVE-2026-93520)

A flaw was found in xorg-x11-server. The X server incorrectly calculates buffer sizes and memory offsets when prepending or appending data to RandR (Resize and Rotate extension) provider properties. A local attacker can exploit this vulnerability by sending specially crafted property update requests, causing memory corruption. This flaw could allow an attacker to escalate privileges or cause a denial of service (DoS) by crashing the X server.(CVE-2026-93521)
