Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-5926-1)
Summary:	The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial' package(s) announced via the USN-5926-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial' package(s) announced via the USN-5926-1 advisory. Vulnerability Insight: Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. (CVE-2021-4155) Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20566) Duoming Zhou discovered that a race condition existed in the SLIP driver in the Linux kernel, leading to a null pointer dereference vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-41858) Tamas Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-42895) 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 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-kvm, linux-lts-xenial' package(s) on Ubuntu 14.04, Ubuntu 16.04. 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
