Description:	Summary: The remote host is missing an update for the 'linux-oem-6.5' package(s) announced via the USN-6479-1 advisory. Vulnerability Insight: Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-42756) Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of- bounds write vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-4881) 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) Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle removal of rules from chain bindings in certain circumstances, leading to 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-2023-5197) Affected Software/OS: 'linux-oem-6.5' 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
