| CVE-2024-21886 | Hig | 7.8 | < 1.20.11-24.el9 | 1.20.11-24.el9 | Feb 28, 2024 | A heap buffer overflow flaw was found in the DisableDevice function in the X.Org server. This issue may lead to an application crash or, in some circumstances, remote code execution in SSH X11 forwarding environments. | |
| CVE-2024-21885 | Hig | 7.8 | < 1.20.11-24.el9 | 1.20.11-24.el9 | Feb 28, 2024 | A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an applicat | |
| CVE-2024-0229 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Feb 9, 2024 | 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 | ||
| CVE-2024-0409 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Jan 18, 2024 | A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. | ||
| CVE-2024-0408 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Jan 18, 2024 | A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access t | ||
| CVE-2023-6816 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Jan 18, 2024 | A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number o | ||
| CVE-2023-6478 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Dec 13, 2023 | 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 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Dec 13, 2023 | 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 inv | ||
| CVE-2023-5380 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Oct 25, 2023 | A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root | ||
| CVE-2023-5367 | — | < 1.20.11-24.el9 | 1.20.11-24.el9 | Oct 25, 2023 | 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/rrprope | ||
| CVE-2023-1393 | — | < 1.20.11-19.el9 | 1.20.11-19.el9 | Mar 30, 2023 | A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will tri | ||
| CVE-2023-0494 | — | < 1.20.11-17.el9 | 1.20.11-17.el9 | Mar 27, 2023 | 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 th | ||
| CVE-2022-46344 | — | < 1.20.11-17.el9 | 1.20.11-17.el9 | Dec 14, 2022 | A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. This issue can lead to local privileges elevation on sy | ||
| CVE-2022-46343 | — | < 1.20.11-17.el9 | 1.20.11-17.el9 | Dec 14, 2022 | 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 | ||
| CVE-2022-46342 | — | < 1.20.11-17.el9 | 1.20.11-17.el9 | Dec 14, 2022 | A vulnerability was found in X.Org.

| CVE-2022-46340 | — | < 1.20.11-17.el9 | 1.20.11-17.el9 | Dec 14, 2022 | 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.
