Ubuntu 22.04 LTS / 23.10 : Linux kernel (AWS) vulnerabilities (USN-6680-3)

high Nessus Plugin ID 192293

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6680-3 advisory.

 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2023-46343)

 It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, 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-2023-51779)

 It was discovered that a race condition existed in the Rose X.25 protocol implementation in the Linux kernel, 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-2023-51782)

 Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

 Jann Horn discovered that the io_uring subsystem in the Linux kernel contained an out-of-bounds access vulnerability. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2023-6560)

 Dan Carpenter discovered that the netfilter subsystem in the Linux kernel did not store data in properly sized memory locations. A local user could use this to cause a denial of service (system crash).
 (CVE-2024-0607)

 Supraja Sridhara, Benedict Schlter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service (guest crash) or possibly execute arbitrary code. (CVE-2024-25744)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
