https://notcve.org/view.php?id=CVE-2023-1989
A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on hdev devices.

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
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 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.8 https://github.com/torvalds/linux/commit/112e66017bff7f2837030f34c2bc19501e9212d5 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230511-0007 https://access.redhat.com/security/cve/CVE-2023-30456 https://bugzilla&# • CWE-358: Improperly Implemented Security Check for Standard •
