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-2021-3975
A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. Se ha encontrado un fallo de uso de memoria previamente liberada en libvirt. • https://access.redhat.com/security/cve/CVE-2021-3975 https://bugzilla.redhat.com/show_bug.cgi?id=2024326 https://github.com/libvirt/libvirt/commit/1ac703a7d0789e46833f4013a3876c2e3af18ec7 https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html https://security.netapp.com/advisory/ntap-20221201-0002 https://ubuntu.com/security/CVE-2021-3975 • CWE-416: Use After Free •
CVSS: 8.8EPSS: 0%CPEs: 20EXPL: 1CVE-2022-1227 – psgo: Privilege escalation in 'podman top'
https://notcve.org/view.php?id=CVE-2022-1227
A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service. Se ha encontrado un fallo de escalada de privilegios en Podman. • https://bugzilla.redhat.com/show_bug.cgi?id=2070368 https://github.com/containers/podman/issues/10941 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://security.netapp.com/advisory/ntap-20240628-0001 https://access.redhat.com/security/cve/CVE-2022-1227 • CWE-269: Improper Privilege Management CWE-281: Improper Preservation of Permissions •

https://notcve.org/view.php?id=CVE-2022-1016
A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. Se ha encontrado un fallo en el kernel de Linux en el archivo net/netfilter/nf_tables_core.c:nft_do_chain, que puede causar un uso de memoria previamente liberada.
