CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions X.Org Server versions prior to 1.20.10
Description A flaw was found in the X.Org Server, specifically an out-of-bounds access in the XkbSetMap function, which may lead to a privilege escalation issue. The highest threat from this issue is to data confidentiality and integrity as well as system availability. This could allow an attacker to access confidential data, compromise their integrity, and cause a denial of service.
Recommendations For versions prior to 1.20.10, update to version 1.20.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the XkbSetMap function until a patch is available.
