QEMU (Quick Emulator) is a set of emulation processor software from Fabrice Bellard, a French personal developer. The software is fast and cross-platform. physmem.c version 7.0.0 and below of QEMU has a denial-of-service vulnerability, which stems from the possibility of uninitialized reads of the translate_fail path, which can be exploited by an attacker to cause a crash of io_readx or io_writex.
