Description

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.

Affected configurations

• qemu qemu (<= 7.1.0) • fedoraproject extra packages for enterprise linux 8.0 • fedoraproject fedora 37 • redhat enterprise linux 8.0
