发布于3月6日3月6日 Members Gentoo Linux: CVE-2023-1393: X.Org X server, XWayland: Multiple Vulnerabilities Severity 7 CVSS (AV:L/AC:L/Au:S/C:C/I:C/A:C) Published 03/30/2023 Created 05/31/2023 Added 05/31/2023 Modified 01/28/2025 Description A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.
