Calendar Grey August 21, 2024
Dist Ubuntu Esm H88
Multiple critical kernel issues are resolved in Ubuntu 16.04 LTS to enhance security and prevent system crashes.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-kvm: Linux kernel for cloud environments

- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux

Kernel contained a race condition, leading to a NULL pointer dereference.

An attacker could possibly use this to cause a denial of service (system

crash). (CVE-2024-22099)

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.

After a standard system update you need to reboot your computer to make
all the necessary changes.

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.
