|---|---|---|---|---|---|---|---|---|
| CVE-2025-26596 | Hig | 0.51 | 7.8 | 0.00 | Feb 25, 2025 | 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 | Hig | 0.51 | 7.8 | 0.00 | Feb 25, 2025 | 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… | ||
| CVE-2025-26594 | Hig | 0.51 | 7.8 | 0.00 | Feb 25, 2025 | 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-2024-9632 | Hig | 0.51 | 7.8 | 0.01 | Oct 30, 2024 | A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions… | ||
| CVE-2024-31083 | Hig | 0.51 | 7.8 | 0.02 | Apr 5, 2024 | A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted… | ||
| CVE-2024-21886 | Hig | 0.51 | 7.8 | 0.01 | 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 | 0.51 | 7.8 | 0.01 | 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… | ||
| CVE-2024-0229 | Hig | 0.51 | 7.8 | 0.01 | 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… | ||
| CVE-2024-0409 | Hig | 0.51 | 7.8 | 0.00 | 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-2023-6377 | Hig | 0.51 | 7.8 | 0.02 | 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… | ||
| CVE-2023-5367 | Hig | 0.51 | 7.8 | 0.01 | 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… | ||
| CVE-2022-4283 | Hig | 0.51 | 7.8 | 0.01 | Dec 14, 2022 | A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems… | ||
| CVE-2022-2320 | Hig | 0.51 | 7.8 | 0.01 | Sep 1, 2022 | A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw… | ||
| CVE-2022-2319 | Hig | 0.51 | 7.8 | 0.00 | Sep 1, 2022 | A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length. | ||

An out-of-bounds access can occur in the SProcXFixesCreatePointerBarrier function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||
| CVE-2021-4008 | Hig | 0.51 | 7.8 | 0.01 | Dec 17, 2021 | A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcRenderCompositeGlyphs function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||
| CVE-2020-14360 | Hig | 0.51 | 7.8 | 0.00 | Jan 20, 2021 | A flaw was found in the X.Org Server before version 1.20.10. An out-of-bounds access in the XkbSetMap function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||
| CVE-2020-25712 | Hig | 0.51 | 7.8 | 0.00 | Dec 15, 2020 | A flaw was found in xorg-x11-server before 1.20.10. A heap-buffer overflow in XkbSetDeviceInfo may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. |
