Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-6777-1)

high Nessus Plugin ID 197215

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6777-1 advisory.

 Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233)

 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:

 - Block layer subsystem;

 - Userspace I/O drivers;

 - Ceph distributed file system;

 - Ext4 file system;

 - JFS file system;

 - NILFS2 file system;

 - Bluetooth subsystem;

 - Networking core;

 - IPv4 networking;

 - IPv6 networking;

 - Logical Link layer;

 - MAC80211 subsystem;

 - Netlink;

 - NFC subsystem;

 - Tomoyo security module; (CVE-2023-52524, CVE-2023-52530, CVE-2023-52601, CVE-2023-52439, CVE-2024-26635, CVE-2023-52602, CVE-2024-26614, CVE-2024-26704, CVE-2023-52604, CVE-2023-52566, CVE-2021-46981, CVE-2024-26622, CVE-2024-26735, CVE-2024-26805, CVE-2024-26801, CVE-2023-52583)

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.
