| Doc Text: |
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's physical address, potentially reading past the end of the bar space into adjacent pages. This could allow a malicious guest user to crash the QEMU process on the host, causing a denial of service. Spice was found to be affected by the same CVE.
