CVE-2017-13673

CVE-2017-13673 describes a denial-of-service vulnerability in QEMU, specifically affecting the VGA display update mechanism when split-screen mode is active. This flaw, rated Medium severity (CVSS 6.5), stems from a miscalculation in the dirty bitmap snapshot region, leading to an assertion failure in the cpu_physical_memory_snapshot_get_dirty function. While the vulnerability could allow a remote, low-privileged attacker to cause a denial of service, there is no evidence of active exploitation, nor are there publicly available exploit codes or significant community discussion surrounding it.
