|---|---|---|---|---|---|
| CVE-2015-0255 | 2 Opensuse, X.org | 2 Opensuse, X Server | 2025-08-29 | 6.4 MEDIUM | N/A |
| X.Org Server (aka xserver and xorg-server) before 1.16.3 and 1.17.x before 1.17.1 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (crash) via a crafted string length value in a XkbSetGeometry request. | |||||
| CVE-2017-12177 | 2 Debian, X.org | 2 Debian Linux, X Server | 2025-08-29 | 7.5 HIGH | 9.8 CRITICAL |
| xorg-x11-server before 1.19.5 was vulnerable to integer overflow in ProcDbeGetVisualInfo function allowing malicious X client to cause X server to crash or possibly execute arbitrary code. | |||||
| CVE-2020-14347 | 3 Canonical, Debian, X.org | 3 Ubuntu Linux, Debian Linux, X Server | 2025-08-29 | 2.1 LOW | 5.5 MEDIUM |
| A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable. | |||||
| CVE-2015-3164 | 2 Opensuse, X.org | 3 Opensuse, X Server, Xorg-server | 2025-08-29 | 3.6 LOW | N/A |
| The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket. | |||||
| CVE-2014-8094 | 3 Debian, Oracle, X.org | 3 Debian Linux, Solaris, X Server | 2025-08-29 | 6.5 MEDIUM | N/A |
| Integer overflow in the ProcDRI2GetBuffers function in the DRI2 extension in X.Org Server (aka xserver and xorg-server) 1.7.0 through 1.16.x before 1.16.3 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request, which triggers an out-of-bounds read or write. | |||||
| CVE-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2025-08-18 | N/A | 7.8 HIGH |
| A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. | |||||
| CVE-2024-0229 | 3 Fedoraproject, Redhat, X.org | 8 Fedora, Enterprise Linux, Enterprise Linux Aus and 5 more | 2025-08-04 | N/A | 7.8 HIGH |
| An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments. | |||||
| CVE-2023-6478 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2025-08-04 | N/A | 7.6 HIGH |
| A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information. | |||||
| CVE-2023-5367 | 4 Debian, Fedoraproject, Redhat and 1 more | 12 Debian Linux, Fedora, Enterprise Linux and 9 more | 2025-08-04 | N/A | 7.8 HIGH |
| A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. | |||||
| CVE-2025-26601 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-16 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers. | |||||
| CVE-2025-26600 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-16 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free. | |||||
| CVE-2025-26599 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later. | |||||
| CVE-2025-26598 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. | |||||
| CVE-2025-26597 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size. | |||||
| CVE-2025-26596 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. | |||||
| CVE-2025-26595 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size. | |||||
| CVE-2025-26594 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-13 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. | |||||
| CVE-2022-46343 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. | |||||
| CVE-2022-46342 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X se | |||||
| CVE-2022-46341 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. | |||||
