NVD Description

Note: Versions mentioned in the description apply only to the upstream virt:rhel/virt-v2v-man-pages-ja package and not the virt:rhel/virt-v2v-man-pages-ja package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
