| 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. | |||||

| 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. | |||||
| CVE-2022-46340 | 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 becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. 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. This issue does not affect systems where client and server use the same byte order. | |||||
| CVE-2011-4028 | 1 X.org | 1 X Server | 2025-04-11 | 1.2 LOW | N/A |
| The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to determine the existence of arbitrary files via a symlink attack on a temporary lock file, which is handled differently if the file exists. | |||||
| CVE-2011-4029 | 1 X.org | 1 X Server | 2025-04-11 | 1.9 LOW | N/A |
| The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file. | |||||
| CVE-2011-4613 | 4 Canonical, Debian, Ubuntu and 1 more | 4 Ubuntu Linux, Debian Linux, Linux and 1 more | 2025-04-11 | 4.6 MEDIUM | N/A |
| The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY. | |||||
| CVE-2025-26600 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26596 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26601 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26598 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26599 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26594 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2025-26597 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-04-10 | 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-2007-6427 | 7 Apple, Canonical, Debian and 4 more | 11 Mac Os X, Ubuntu Linux, Debian Linux and 8 more | 2025-04-09 | 9.3 HIGH | N/A |
| The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990. | |||||
| CVE-2025-26595 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-03-17 | 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-2023-0494 | 3 Fedoraproject, Redhat, X.org | 18 Fedora, Enterprise Linux, Enterprise Linux Aus and 15 more | 2025-02-24 | N/A | 7.8 HIGH |
| A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. | |||||
| CVE-2024-0229 | 3 Fedoraproject, Redhat, X.org | 8 Fedora, Enterprise Linux, Enterprise Linux Aus and 5 more | 2024-11-23 | 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 | 2024-11-21 | 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-2023-6377 | 4 Debian, Redhat, Tigervnc and 1 more | 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-11-21 | 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. | |||||
