It could occur while performing UAR read operation, as it did not define a routine to handle it. A guest user/process could use this flaw to crash QEMU process on host, resulting in DoS. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg03066.html This issue was reported by Li Qiang. Thank you. -- Prasad J Pandit / Red Hat Product Security Team 47AF CE69 3A90 54AA 9045 1053 DD13 3D32 FE5B 041F
