CVE-2023-1829 – Use-after-free in tcindex (traffic control index filter) in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-1829
12 Apr 2023 — A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.

CVE-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 •
