CVE-2026-33999
Xorg: xwayland: x.org x server: denial of service via integer underflow in xkb compatibility map handling
Overview
Description
A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of service (DoS) or other severe impacts.
