Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

  • ntfs-3g: heap-based buffer overflow in ntfsck (CVE-2021-46790)
  • QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU exhaustion (CVE-2022-3165)
  • ntfs-3g: crafted NTFS image can cause heap exhaustion in ntfs_get_attribute_value (CVE-2022-30784)
  • ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_names_full_collate (CVE-2022-30786)
  • ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_mft_rec_alloc (CVE-2022-30788)
  • ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_check_log_client_array (CVE-2022-30789)
  • tpm2: TCG TPM2.0 implementations vulnerable to memory corruption (CVE-2023-1018)
