Test ID:	1.3.6.1.4.1.25623.1.0.845441
Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-5518-1)
Summary:	The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-gcp, linux-gke, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) announced via the USN-5518-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-gcp, linux-gke, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) announced via the USN-5518-1 advisory. Vulnerability Insight: It was discovered that the eBPF implementation in the Linux kernel did not properly prevent writes to kernel objects in BPF_BTF_LOAD commands. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-0500) It was discovered that the Marvell NFC device driver implementation in the Linux kernel did not properly perform memory cleanup operations in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1734) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1789) Duoming Zhou discovered a race condition in the NFC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1974) Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not properly prevent context switches from occurring during certain atomic context operations. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2022-1975) Minh Yuan discovered that the floppy driver in the Linux kernel contained a race condition in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-33981) Affected Software/OS: 'linux, linux-aws, linux-azure, linux-gcp, linux-gke, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) on Ubuntu 22.04. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
