USN-5000-2: Linux kernel (KVM) vulnerabilities

USN-5000-1 fixed vulnerabilities in the Linux kernel for Ubuntu 20.04 LTS and the Linux HWE kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux KVM kernel for Ubuntu 20.04 LTS. Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of...

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads leading to disclosure of stack content via side-channel attacks aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.
