CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-30456 – kernel: KVM: nVMX: missing consistency checks for CR0 and CR4
https://notcve.org/view.php?id=CVE-2023-30456
10 Apr 2023 — An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64 lacks consistency checks for CR0 and CR4. A flaw was found in the KVM's Intel nested virtualization feature (nVMX). The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. In rare circumstances (i.e., kvm_intel module loaded with parameters nested=1 and ept=0) this could allow a malicious guest to crash the host system, causing a denial of service. • http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html • CWE-358: Improperly Implemented Security Check for Standard •

27 Mar 2023 — A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms. • https://bugzilla.redhat.com/show_bug.cgi?id=2019643 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

27 Mar 2023 — In the Linux kernel through 6.2.8, net/bluetooth/hci_sync.c allows out-of-bounds access because amp_init1[] and amp_init2[] are supposed to have an intentionally invalid element, but do not. An out-of-bounds (OOB) memory access flaw was found in net/bluetooth/hci_sync.c due to a missing exit patch while in loop in amp_init1[] and amp_init2[]. This issue could allow an attacker to leak internal kernel information. • https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=95084403f8c070ccf5d7cbe72352519c1798a40a • CWE-125: Out-of-bounds Read •
