Memory leak in the audio/audio.c in QEMU (aka Quick Emulator) allows remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
