https://notcve.org/view.php?id=CVE-2023-3019
A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. • https://access.redhat.com/errata/RHSA-2024:0135 https://access.redhat.com/errata/RHSA-2024:0404 https://access.redhat.com/errata/RHSA-2024:0569 https://access.redhat.com/errata/RHSA-2024:2135 https://access.redhat.com/security/cve/CVE-2023-3019 https://bugzilla.redhat.com/show_bug.cgi?id=2222351 https://security.netapp.com/advisory/ntap-20230831-0005 • CWE-416: Use After Free •
CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-3354 – Improper i/o watch removal in tls handshake can lead to remote unauthenticated denial of service
https://notcve.org/view.php?id=CVE-2023-3354
A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. • https://access.redhat.com/security/cve/CVE-2023-3354 https://bugzilla.redhat.com/show_bug.cgi?id=2216478 https://lists.debian.org/debian-lts-announce/2024/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MURWGXDIF2WTDXV36T6HFJDBL632AO7R • CWE-476: NULL Pointer Dereference •
