Descriptions

An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled.

Se descubrió un problema en QEMU 7.1.0 a 8.2.1. Register_vfs en hw/pci/pcie_sriov.c no configura NumVFs en PCI_SRIOV_TOTAL_VF y, por lo tanto, la interacción con hw/nvme/ctrl.c no se maneja correctamente.

This update for qemu fixes the following issues. Fixed buffer overflow via invalid SR/IOV NumVFs value. Fixed integer overflow results in buffer overflow via SCSI command. Fixed stack buffer overflow in virtio_net_flush_tx. Fixed out-of-bounds read in pvrdma_ring_next_elem_read. Fixed invalid NumVFs value handled in NVME SR/IOV implementation. The following non-security bug was fixed. Removing in-use mediated device should fail with error message instead of hang.
