Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-5970-1)
Summary:	The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-gcp, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) announced via the USN-5970-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-gcp, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) announced via the USN-5970-1 advisory. Vulnerability Insight: It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2022-2196) It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-42328, CVE-2022-42329) Gerald Lee discovered that the USB Gadget file system implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4382) Jose Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did not properly protect against indirect branch prediction attacks in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2023-0045) It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-0266) It was discovered that the io_uring subsystem in the Linux kernel contained 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-2023-0469) It was discovered that the CIFS network file system implementation in the Linux kernel contained a user-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-1195) It was discovered that the RNDIS USB driver in the Linux kernel contained an integer overflow vulnerability. A local attacker with physical access could plug in a malicious USB device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-23559) Affected Software/OS: 'linux, linux-aws, linux-azure, linux-gcp, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi' package(s) on Ubuntu 22.10. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
