Summary
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.

Summary
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 that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.

FKIE_CVE-2023-6816
Vulnerability from fkie_nvd - Published: 2024-01-18 05:15 - Updated: 2025-08-29 13:42
Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary
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 of buttons, leading to a heap overflow if a bigger value was used.

FKIE_CVE-2023-1393
Vulnerability from fkie_nvd - Published: 2023-03-30 21:15 - Updated: 2025-08-29 13:42
Severity ?

Summary
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 trigger a use-after-free later.

FKIE_CVE-2022-4283
Vulnerability from fkie_nvd - Published: 2022-12-14 21:15 - Updated: 2025-08-29 13:42
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary
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 where the X server is running privileged and remote code execution for ssh X forwarding sessions.

Summary
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 allows an attacker to escalate privileges and execute arbitrary code in the context of root.

CVE-2024-0408 (GCVE-0-2024-0408)
Vulnerability from cvelistv5 – Published: 2024-01-18 15:40 – Updated: 2025-11-20 07:08
VLAI?
Summary
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 that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.
Severity ?
5.5 (Medium)
CWE
- CWE-158 - Improper Neutralization of Null Byte or NUL Character

CVE-2023-6816 (GCVE-0-2023-6816)
Vulnerability from cvelistv5 – Published: 2024-01-18 04:31 – Updated: 2025-11-20 07:07
VLAI?
Summary
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 of buttons, leading to a heap overflow if a bigger value was used.
Severity ?
9.8 (Critical)
CWE
- CWE-787 - Out-of-bounds Write

CVE-2023-1393 (GCVE-0-2023-1393)
Vulnerability from cvelistv5 – Published: 2023-03-30 00:00 – Updated: 2025-02-14 15:43

Summary
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 trigger a use-after-free later.

Summary
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 where the X server is running privileged and remote code execution for ssh X forwarding sessions.

CVE-2022-2320 (GCVE-0-2022-2320)
Vulnerability from cvelistv5 – Published: 2022-09-01 00:00 – Updated: 2024-08-03 00:32
VLAI?
Summary
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 allows an attacker to escalate privileges and execute arbitrary code in the context of root.
Severity ?
No CVSS data available.

CVE-2024-0408 (GCVE-0-2024-0408)
Vulnerability from nvd – Published: 2024-01-18 15:40 – Updated: 2025-11-20 07:08
VLAI?
Summary
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 that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.
Severity ?
5.5 (Medium)
CWE

CVE-2023-6816 (GCVE-0-2023-6816)
Vulnerability from nvd – Published: 2024-01-18 04:31 – Updated: 2025-11-20 07:07
VLAI?
Summary
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 of buttons, leading to a heap overflow if a bigger value was used.
Severity ?
9.8 (Critical)
CWE
- CWE-787 - Out-of-bounds Write

CVE-2023-1393 (GCVE-0-2023-1393)
Vulnerability from nvd – Published: 2023-03-30 00:00 – Updated: 2025-02-14 15:43

Summary
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 trigger a use-after-free later.

Summary
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 where the X server is running privileged and remote code execution for ssh X forwarding sessions.

CVE-2022-2320 (GCVE-0-2022-2320)
Vulnerability from nvd – Published: 2022-09-01 00:00 – Updated: 2024-08-03 00:32
VLAI?
Summary
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 allows an attacker to escalate privileges and execute arbitrary code in the context of root.
Severity ?
No CVSS data available.
