| 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-2018-14665 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2025-08-29 | 7.2 HIGH | 6.6 MEDIUM |
| A flaw was found in xorg-x11-server before 1.20.3. An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges. | |||||
| CVE-2022-2320 | 1 X.org | 1 X Server | 2025-08-29 | N/A | 7.8 HIGH |
| 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. | |||||
