CVE-2023-39198

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.
