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-gcp, linux-gcp-5.4, linux-gke, linux-gke-5.4, linux-gkeop, linux-gkeop-5.4, linux-hwe-5.4, linux-ibm, linux-kvm, linux-oracle, linux-oracle-5.4' package(s) announced via the USN-5267-2 advisory. Vulnerability Insight: USN-5267-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression that caused the kernel to freeze when accessing CIFS shares in some situations. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that the Bluetooth subsystem in the Linux kernel contained 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-2021-3640) Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, 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-2021-3752) Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds checking in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42739) Affected Software/OS: 'linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, 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-kvm, linux-oracle, linux-oracle-5.4' package(s) on Ubuntu 18.04, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 7.9 CVSS Vector: AV:A/AC:M/Au:N/C:C/I:C/A:C
