Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6443-1)
Summary:	The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6443-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6443-1 advisory. Vulnerability Insight: Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-42752) Kyle Zeng discovered that the IPv4 Resource Reservation Protocol (RSVP) classifier implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). Please note that kernel packet classifier support for RSVP has been removed to resolve this vulnerability. (CVE-2023-42755) 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) 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-6.1' package(s) on Ubuntu 22.04. Solution: Please install the updated package(s). CVSS Score: 5.7 CVSS Vector: AV:L/AC:L/Au:S/C:P/I:P/A:C
