https://notcve.org/view.php?id=CVE-2022-2196
09 Jan 2023 — A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a A flaw was found in the KVM's Intel nested virtualization feature (nVMX).

09 Jan 2023 — A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations.
