CVE-2024-26327

A flaw was found in the SR/IOV emulation support of QEMU. The registervfs function in hw/pci/pciesriov.c mishandled the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF Virtual Function implementations. This flaw allows a malicious guest to crash QEM...
