CVE-2021-20257

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read during sdhci_write() operations. A guest OS user can crash the QEMU process.(CVE-2020-13253)

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:Rocky Linux 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):

• QEMU: off-by-one error in mode_sense_page() in hw/scsi/scsi-disk.c (CVE-2021-3930)

• QEMU: net: e1000: infinite loop while processing transmit descriptors (CVE-2021-20257)
