CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2021-3839 – DPDK: out-of-bounds read/write in vhost_user_set_inflight_fd() may lead to crash
https://notcve.org/view.php?id=CVE-2021-3839
A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability. Se ha encontrado un fallo en la biblioteca vhost de DPDK. La función vhost_user_set_inflight_fd() no comprueba "msg-)payload.inflight.num_queues", causando posiblemente una lectura/escritura de memoria fuera de límites. • https://access.redhat.com/security/cve/CVE-2021-3839 https://bugzilla.redhat.com/show_bug.cgi?id=2025882 https://github.com/DPDK/dpdk/commit/6442c329b9d2ded0f44b27d2016aaba8ba5844c5 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-14377
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00006.html http://www.openwall.com/lists/oss-security/2021/01/04/1 http://www.openwall.com/lists/oss-security/2021/01/04/2 http://www.openwall.com/lists/oss-security/2021/01/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1879472 https://usn.ubuntu.com/4550-1 https://www.openwall.com/lists/oss-security/2020/09/28/3 • CWE-125: Out-of-bounds Read •
