CVSS: 6.5EPSS: 0%CPEs: 12EXPL: 0CVE-2022-0669 – dpdk: sending vhost-user-inflight type messages could lead to DoS
https://notcve.org/view.php?id=CVE-2022-0669
A flaw was found in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the vhost-user slave. By sending such messages continuously, the vhost-user master exhausts available fd in the vhost-user slave process, leading to a denial of service. Se ha encontrado un fallo en dpdk. Este fallo permite a un vhost-user master malicioso adjuntar un número inesperado de fds como datos auxiliares a los mensajes VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD que no son cerrados por el vhost-user slave. • https://access.redhat.com/security/cve/CVE-2022-0669 https://bugs.dpdk.org/show_bug.cgi?id=922 https://bugzilla.redhat.com/show_bug.cgi?id=2055793 https://github.com/DPDK/dpdk/commit/af74f7db384ed149fe42b21dbd7975f8a54ef227 https://security-tracker.debian.org/tracker/CVE-2022-0669 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
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 •
