Moderate: qemu-kvm security, bug fix, and enhancement update
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.
The following packages have been upgraded to a later upstream version: qemu-kvm (7.0.0). (BZ#2064757)
Security Fix(es):
-
QEMU: hcd-ehci: DMA reentrancy issue leads to use-after-free (CVE-2021-3750)
-
QEMU: fdc: heap buffer overflow in DMA read data transfers (CVE-2021-3507)
-
QEMU: intel-hda: segmentation fault due to stack overflow (CVE-2021-3611)
-
QEMU: NULL pointer dereference in pci_write() in hw/acpi/pcihp.c (CVE-2021-4158)

ELSA-2022-7967: qemu-kvm security, bug fix, and enhancement update (MODERATE)
A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory.
