Does this matter?
Lower severity and a low EPSS score (1.21%). Track it; it rarely justifies an emergency change on its own.

Quick Emulator (Qemu) built with the 'chardev' backend support is vulnerable to a use after free issue. It could occur while hotplug and unplugging the device in the guest. A guest user/process could use this flaw to crash a Qemu process on the host resulting in DoS.
