CVE-2022-4144 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
