Vulnerability Title
Xorg: xwayland: x.org x server: information exposure and denial of service via out-of-bounds memory access
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the X.Org X server's XKB key types request validation. A local attacker could send a specially crafted request to the X server, leading to an out-of-bounds memory access vulnerability. This could result in the disclosure of sensitive information or cause the server to crash, leading to a Denial of Service (DoS). In certain configurations, higher impact outcomes may be possible.
