- Summary
- CVE-2023-6693 affecting package qemu for versions less than 8.2.0-13
- Details
-
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtionetflushtx function if guest features VIRTIONETFHASHREPORT, VIRTIOFVERSION1 and VIRTIONETFMRGRXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the
out_sgvariable could be used to read a part of process memory and send it to the wire, causing an information leak. - References
