QEMU Buffer Overflow Vulnerability (CNVD-2022-84156)

QEMU Quick Emulator is a set of emulation processor software by Fabrice Bellard, a French personal developer. The software is fast and cross-platform. QEMU suffers from a buffer overflow vulnerability that stems from a lack of validation of the input data size or length in the readerstrecord and...

CVE-2022-4172

An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table ERST device of QEMU in the readerstrecord and writeerstrecord functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could...
