| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H |
Name of the Vulnerable Software and Affected Versions
X.Org X Server versions 2:21.1.16-1ubuntu1.2 and earlier
X.Org X Server (affected versions not specified)
Description
The X.Org X Server contains flaws in memory handling and client resource cleanup. Specifically, the X Keyboard (Xkb) extension improperly manages data structures during client disconnections, leading to a use-after-free condition. This can result in memory corruption, a crash, or potentially allow an attacker to gain code execution. The issue occurs when the software frees certain data structures without properly detaching related resources.
