Detailsinfo

A vulnerability was found in QEMU (Virtualization Software) (affected version unknown) and classified as critical. This issue affects the function read_erst_record/write_erst_record of the component ERST Device Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.

The weakness was published 11/30/2022 as 1268. The advisory is shared at gitlab.com. The identification of this vulnerability is CVE-2022-4172 since 11/28/2022. Technical details are known, but no exploit is available.
