CVE: - CVE-2023-33951 Aliases: - ZDI-23-707 - ZDI-CAN-20110 Bug Title: - CVE-2023-33951 - kernel: vmwgfx: race condition leading to information disclosure vulnerability Reported Date: - 2023-06-28 12:16 UTC Modified Date: - 2023-09-06 08:30 UTC Product and Component: - Product: Security Response - Component: vulnerability OS: - Linux Priority: - medium Description: - A race condition vulnerability was found in the vmwgfx driver in the Linux kernel. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of GEM objects, where the lack of proper locking when performing operations on an object allows an attacker to leverage this vulnerability to disclose information in the context of the kernel.
