May 16, 2024<\/p>\n
linux, linux-aws, linux-azure-4.15, linux-gcp-4.15, linux-hwe, linux-kvm,
linux-oracle vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux: Linux kernel
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems
– linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
– linux-kvm: Linux kernel for cloud environments
– linux-oracle: Linux kernel for Oracle Cloud systems
– linux-hwe: Linux hardware enablement (HWE) kernel<\/p>\n
Details:<\/p>\n
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)<\/p>\n
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;

After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\n
