| CVE-2023-6478 | Hig | 0.50 | 7.6 | 0.02 | 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-2026-55999 | Hig | 0.48 | 8.5 | 0.00 | Jul 8, 2026 | Local attackers with a X connection able to provide PCX fonts to the X server xorg-server before 21.2.24 and xwayland before 24.1.13 could cause a heap buffer overflow via SetFont due to missing glyph boundary checks. | ||
| CVE-2025-62230 | Hig | 0.47 | 7.3 | 0.00 | Oct 30, 2025 | A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a… | ||
| CVE-2025-62229 | Hig | 0.47 | 7.3 | 0.00 | Oct 30, 2025 | A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash,… | ||
| CVE-2025-62231 | Hig | 0.47 | 7.3 | 0.00 | Oct 30, 2025 | A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to… | ||
| CVE-2026-56000 | Hig | 0.44 | 7.8 | 0.00 | Jul 8, 2026 | Local attackers with a X connection able to provide GLX commit to the X server xorg-server before 21.2.24 and xwayland before 24.1.13 could cause a Heap Use After Free, due to CommonMakeCurrent() pointing into potentially reallocated memory. | ||
| CVE-2026-50263 | Med | 0.36 | 5.5 | 0.00 | Jun 5, 2026 | A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure. | ||
| CVE-2026-50262 | Med | 0.36 | 5.5 | 0.00 | Jun 5, 2026 | An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists… | ||
| CVE-2024-0408 | Med | 0.36 | 5.5 | 0.00 | 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… | ||
| CVE-2023-5380 | Med | 0.31 | 4.7 | 0.01 | 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… |
