In versions 0.20210107, function `pci_vtsock_proc_tx` in `virtio-sock` can lead to to uninitialized memory use. In this situation, there is a check for the return value to be less or equal to `VTSOCK_MAXSEGS`, but that check is not sufficient because the function can return `-1` if it finds an error it cannot recover from. Moreover, the negative return value will be used by `iovec_pull` in a while condition that can further lead to more corruption because the function is not designed to handle a negative `iov_len`. This issue may lead to a guest crashing the host causing a denial of service and, under certain circumstance, memory corruption. This issue is fixed in commit af5eba2360a7351c08dfd9767d9be863a50ebaba.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/58500"}, {"timestamp": "2023-02-28T21:30:17Z", "date_only": false, "value": "2023-02-28T21:30:17Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-8J79-G729-4VV7", "record": "GHSA-8J79-G729-4VV7", "field": "modified"}, {"timestamp": "2023-06-26T17:47:00Z", "date_only": false, "value": "2023-06-26T17:47Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-32846", "record": "GSD-2021-32846", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-12-13T01:23:09.394Z", "date_only": false, "value": "2023-12-13T01:23:09.394826Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-32846", "record": "GSD-2021-32846", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-03T23:33:56.113Z", "date_only": false, "value": "2024-08-03T23:33:56.113Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-32846", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2025-03-10T20:57:20.315Z", "date_only": false, "value": "2025-03-10T20:57:20.315278Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-32846", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2025-03-10T20:57:20.315Z", "date_only": false, "value": "2025-03-10T20:57:20.315278Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-32846", "record": "FKIE_CVE-2021-32846", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2025-03-10T21:09:47.105Z", "date_only": false, "value": "2025-03-10T21:09:47.105Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-32846", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-03-10T21:09:47.105Z", "date_only": false, "value": "2025-03-10T21:09:47.105Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-32846", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T03:53:44.990Z", "date_only": false, "value": "2026-06-17T03:53:44.990", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-32846", "record": "FKIE_CVE-2021-32846", "field": "lastModified"}]}
