CVE-2017-5579 describes a memory leak vulnerability in the serial_exit_core function within QEMU's hw/char/serial.c, affecting various QEMU and Debian Linux distributions. This flaw allows a local, privileged guest OS user to trigger a denial of service on the host by repeatedly unplugging devices, leading to host memory exhaustion and a QEMU process crash. With a CVSS score of 6.5 (Medium), it requires local access and low privileges, but has a high impact on availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
