https://notcve.org/view.php?id=CVE-2021-35561
Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Utility). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • https://lists.debian.org/debian-lts-announce/2021/11/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6EUURAQOIJYFZHQ7DFZCO6IKDPIAWTNK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7WTVCIVHTX3XONYOEGUMLKCM4QEC6INT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJILEHYV2U37HKMGFEQ7CAVOV4DUWW2O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTYZWIXDFUV2H57YQZJWPOD3 • CWE-770: Allocation of Resources Without Limits or Throttling •

CVSS: 8.8EPSS: 0%CPEs: 76EXPL: 1CVE-2021-3656 – kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
https://notcve.org/view.php?id=CVE-2021-3656
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. Se ha encontrado un fallo en el código AMD de KVM para soportar la virtualización anidada SVM. • https://github.com/rami08448/CVE-2021-3656-Demo https://bugzilla.redhat.com/show_bug.cgi?id=1983988 https://git.kernel.org/pub/scm/virt/kvm/kvm.git/commit/?id=c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://github.com/torvalds/linux/commit/c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3656 • CWE-862: Missing Authorization •
