A heap buffer overflow in handling GLX RenderLarge request where dataBytes exceeds cmdlen in X.org X server before 21.1.25 and XWayland before 24.1.14 that could be be triggered by an authenticated X client could cause crashes or code execution in X server context.
CVE-2026-93516 1 X.org 3 X Server, Xorg-x11-server, Xwayland 2026-10-28 5.5 Medium
A use-after-free caused by lack of lifecycle management when adding / removing XInput master devices in X.org X Server before 21.1.25 and XWayland before 24.1.14 could be used by authenticated X Clients to crash the X server or potentially execute code in X server context.
CVE-2026-93515 1 X.org 3 X Server, Xorg-x11-server, Xwayland 2026-10-28 6.1 Medium
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.
CVE-2026-109089 1 X.org 1 Libxi 2026-10-27 7.5 High
A buffer overflow when handling DEVICE_RESOLUTION in libXi before 1.8.4 could overflow a heap, triggered by a malicious X server.
CVE-2026-88812 1 X.org 3 Xorg-server, Xorg-x11-server, Xwayland 2026-10-27 7.8 High
A double free in XKB SetGeometryin X.Org X Server before 21.1.25 and X Wayland before 24.1.14 could be used by attached clients to cause a crash or potentially code in the x server context.
CVE-2026-109090 1 X.org 1 Libxi 2026-10-27 7.5 High
A malicious X server could cause a heap overflow by injecting a large DEVICE_ENABLE reply when processed by libXi before 1.8.4.
CVE-2026-109088 1 X.org 1 Libxtst 2026-10-27 6.5 Medium
A malicious X server could send malformed  RECORD EnableContext reolies that can cause a X client using the parse_reply_call_callback function in libXtst before 1.2.6 to enter a endless loop.
CVE-2026-93520 1 X.org 1 Xorg-server 2026-10-22 7.8 High
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-2026-93536 1 X.org 1 X Server 2026-10-19 5.3 Medium
A flaw was found in the X.Org Server. When a window is removed during an active gesture, the server fails to clean up references to the destroyed window in its gesture tracking data. A local attacker can exploit this flaw to cause a use-after-free condition—where the system accesses memory after it has been released—potentially leading to unauthorized information disclosure or a denial of service (DoS).
CVE-2026-93523 1 X.org 1 X Server 2026-10-18 7.8 High
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.
CVE-2026-93524 1 X.org 1 X Server 2026-10-18 3.3 Low
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.
CVE-2026-94282 2 Libxi, X.org 2 Libxi, Libxi 2026-10-04 5.6 Medium
An out-of-bounds read in libXi's XI2 enter/leave/focus cookie conversion in libXi before 1.8.4 could be used by malicious X server to crash an attached X client.
CVE-2026-94286 1 X.org 1 Libxtst 2026-09-30 7.1 High
An out-of-bounds read in libXtst's RECORD reply parser in libXtst before 1.2.6 could be used by malicious X servers to crash attached X clients.
CVE-2026-94285 1 X.org 1 Libx11 2026-09-30 5.1 Medium
An out-of-bounds read in libX11's byte-oriented codeset parser in libX11 before 1.8.14 could be used by malicious X servers to crash attached X clients.
CVE-2026-94284 1 X.org 1 Libx11 2026-09-30 5.5 Medium
An out-of-bounds read vulnerability in libX11's XIM trigger-key registration parser in libX11 before 1.8.14 could be used by malicious X servers to crash attached X clients.
CVE-2026-94283 1 X.org 1 Libx11 2026-09-30 6.5 Medium
An out-of-bounds read vulnerability in libX11's XIM (X Input Method) attribute parser in libX11 before 1.8.14 could be used by malicious X servers to crash attached X clients.
CVE-2026-94287 1 X.org 1 Libxpm 2026-09-28 5.5 Medium
A denial of service via unsigned underflow in libXpm's write path in libXpm before 3.5.19 could be used by local attackers to cause unbounded CPU usage and memory exhaustion.
CVE-2026-93541 1 X.org 1 Libxi 2026-09-25 6.5 Medium
An out-of-bounds read in libXi's XQueryDeviceState() in libXi before 1.8.4 could be used by a
CVE-2026-93545 1 X.org 1 Libxi 2026-09-25 6.5 Medium
An out-of-bounds read in libXi's XListInputDevices() in libXi before 1.8.4 could be used by malicious X servers to crash an attached X client.
