CVE-2023-39198: Kernel: qxl: race condition leading to use-after-free in qxl_mode_dumb_create()

Published Jun 28, 2023
·
Updated

A race condition leading to a use-after-free issue was found in the QXL driver in the Linux kernel.

Other sources

A race condition was found in the QXL driver in the Linux kernel. The qxlmodedumbcreate() function dereferences the qobj returned by the qxlgemobjectcreatewithhandle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.

— Launchpad

Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition in the QXL driver. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges or cause a denial of service condition.
