Ubuntu 14.04 LTS / 16.04 LTS : Linux kernel vulnerabilities (USN-6938-1)

high Nessus Plugin ID 204920

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6938-1 advisory.

 It was discovered that the device input subsystem in the Linux kernel did not properly handle the case when an event code falls outside of a bitmap. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-48619)

 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 in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

 Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-25739)

 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:

 - GPU drivers;

 - HID subsystem;

 - I2C subsystem;

 - Input Device Drivers (Mouse);

 - MTD block device drivers;

 - Network drivers;

 - TTY drivers;

 - USB subsystem;

 - File systems infrastructure;

 - F2FS file system;

 - SMB network file system;

 - BPF subsystem;

 - B.A.T.M.A.N. meshing protocol;

 - Bluetooth subsystem;

 - IPv4 networking;

 - IPv6 networking;

 - Netfilter;

 - Unix domain sockets;

 - Wireless networking; (CVE-2024-26901, CVE-2021-46932, CVE-2024-26857, CVE-2024-26882, CVE-2024-26934, CVE-2023-52449, CVE-2024-35982, CVE-2021-46933, CVE-2023-52620, CVE-2023-52444, CVE-2024-26923, CVE-2023-52469, CVE-2024-26886, CVE-2024-36902, CVE-2023-52436, CVE-2024-36016, CVE-2024-26884, CVE-2021-46960, CVE-2021-47194, CVE-2023-52752, CVE-2024-27020, CVE-2024-26840, CVE-2024-35997, CVE-2024-35984, CVE-2024-35978)

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.
