Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6045-1)
Summary:	The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial' package(s) announced via the USN-6045-1 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-6045-1 advisory. Vulnerability Insight: It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829) Gwnaun Jung discovered that the SFB packet scheduling implementation 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-2022-3586) Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver 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-2022-4095) It was discovered that the TIPC protocol implementation in the Linux kernel did not properly validate the queue of socket buffers (skb) when handling certain UDP packets. A remote attacker could use this to cause a denial of service. (CVE-2023-1390) It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670) 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
