Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service."}],"problemTypes":[{"descriptions":[{"cweId":"CWE-770","description":"CWE-770","lang":"en","type":"CWE"}]}],"providerMetadata":{"dateUpdated":"2022-09-05T05:06:17.000Z","orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat"},"references":[{"tags":["x_refsource_MISC"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1955695"},{"tags":["x_refsource_MISC"],"url":"https://www.openwall.com/lists/oss-security/2021/05/05/5"},{"tags":["x_refsource_MISC"],"url":"https://gitlab.com/qemu-project/qemu/-/commit/7ec54f9eb62b5d177e30eb8b1cad795a5f8d8986"},{"tags":["x_refsource_MISC"],"url":"https://gitlab.com/qemu-project/qemu/-/commit/05a40b172e4d691371534828078be47e7fff524c"},{"tags":["x_refsource_CONFIRM"],"url":"https://security.netapp.com/advisory/ntap-20210708-0008/"},{"name":"[debian-lts-announce] 20210902 [SECURITY] [DLA 2753-1] qemu security update","tags":["mailing-list","x_refsource_MLIST"],"url":"https://lists.debian.org/debian-lts-announce/2021/09/msg00000.html"},{"name":"GLSA-202208-27","tags":["vendor-advisory","x_refsource_GENTOO"],"url":"https://security.gentoo.org/glsa/202208-27"},{"name":"[debian-lts-announce] 20220905 [SECURITY] [DLA 3099-1] qemu security update","tags":["mailing-list","x_refsource_MLIST"],"url":"https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html"}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T17:01:07.589Z"},"title":"CVE Program Container","references":[{"tags":["x_refsource_MISC","x_transferred"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1955695"},{"tags":["x_refsource_MISC","x_transferred"],"url":"https://www.openwall.com/lists/oss-security/2021/05/05/5"},{"tags":["x_refsource_MISC","x_transferred"],"url":"https://gitlab.com/qemu-project/qemu/-/commit/7ec54f9eb62b5d177e30eb8b1cad795a5f8d8986"},{"tags":["x_refsource_MISC","x_transferred"],"url":"https://gitlab.com/qemu-project/qemu/-/commit/05a40b172e4d691371534828078be47e7fff524c"},{"tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://security.netapp.com/advisory/ntap-20210708-0008/"},{"name":"[debian-lts-announce] 20210902 [SECURITY] [DLA 2753-1] qemu security update","tags":["mailing-list","x_refsource_MLIST","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/09/msg00000.html"},{"name":"GLSA-202208-27","tags":["vendor-advisory","x_refsource_GENTOO","x_transferred"],"url":"https://security.gentoo.org/glsa/202208-27"},{"name":"[debian-lts-announce] 20220905 [SECURITY] [DLA 3099-1] qemu security update","tags":["mailing-list","x_refsource_MLIST","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html"}]}]},"cveMetadata":{"assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","assignerShortName":"redhat","cveId":"CVE-2021-3527","datePublished":"2021-05-26T21:13:56.000Z","dateReserved":"2021-04-30T00:00:00.000Z","dateUpdated":"2024-08-03T17:01:07.589Z","state":"PUBLISHED"},"dataType":"CVE_RECORD","dataVersion":"5.1"}
