Test ID:	1.3.6.1.4.1.25623.1.1.12.2023.6461.1
Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6461-1)
Summary:	The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6461-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6461-1 advisory. Vulnerability Insight: Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-31085) Marek Marczykowski-Gorecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service (paravirtualized device unavailability). (CVE-2023-34324) Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-39189) Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4244) Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference vulnerability. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-42754) It was discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel did not properly handle network packets in certain conditions, 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-2023-4921) It was discovered that the SMB network file sharing protocol implementation in the Linux kernel did not properly handle certain error conditions, 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-2023-5345) Affected Software/OS: 'linux-oem-6.1' package(s) on Ubuntu 22.04. 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
