Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the linux package has been released.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6688-1 advisory.

    Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly     handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a     guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

    It was discovered that the Habana's AI Processors driver in the Linux kernel did not properly initialize     certain data structures before passing them to user space. A local attacker could use this to expose     sensitive information (kernel memory). (CVE-2023-50431)

    Murray McAllister discovered that the VMware Virtual GPU DRM driver in the Linux kernel did not properly     handle memory objects when storing surfaces, leading to a use-after-free vulnerability. A local attacker     in a guest VM could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-5633)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this     to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-6610)

    It was discovered that the VirtIO subsystem in the Linux kernel did not properly initialize memory in some     situations. A local attacker could use this to possibly expose sensitive information (kernel memory).
    (CVE-2024-0340)

    Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element     deactivation in certain cases, 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-2024-1085)

    Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict     parameters in certain cases, 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-2024-1086)

    Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-     bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system     crash). (CVE-2024-23849)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to     a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a     denial of service (system crash). (CVE-2024-24860)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:
