Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-azure-fde, linux-gcp, linux-gcp-5.4, linux-gke, linux-gke-5.4, linux-gkeop, linux-gkeop-5.4, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4' package(s) announced via the USN-5338-1 advisory. Vulnerability Insight: Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges. (CVE-2022-0492) Jurgen Gross discovered that the Xen subsystem within the Linux kernel did not adequately limit the number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a driver domain could use this to cause a denial of service in other guest VMs. (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713) Jurgen Gross discovered that the Xen network backend driver in the Linux kernel did not adequately limit the amount of queued packets when a guest did not process them. An attacker in a guest VM can use this to cause a denial of service (excessive kernel memory consumption) in the network backend domain. (CVE-2021-28714, CVE-2021-28715) It was discovered that the simulated networking device driver for the Linux kernel did not properly initialize memory in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-4135) Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976) It was discovered that the ARM Trusted Execution Environment (TEE) subsystem in the Linux kernel contained a race condition leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-44733) It was discovered that the Phone Network protocol (PhoNet) implementation in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45095) It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45480) Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435) It was discovered that the KVM implementation for s390 systems in the Linux kernel did not properly prevent memory operations on PVM guests that were in non-protected mode. A local attacker could use this to obtain unauthorized memory write access. (CVE-2022-0516) Affected Software/OS: 'linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-azure-fde, linux-gcp, linux-gcp-5.4, linux-gke, linux-gke-5.4, linux-gkeop, linux-gkeop-5.4, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4' package(s) on Ubuntu 18.04, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 9.0 CVSS Vector: AV:N/AC:L/Au:S/C:C/I:C/A:C
