Ubuntu Security Notice USN-7148-1
December 10, 2024
linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
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:
Lyu Tao discovered that the NFS implementation in the Linux kernel did not
properly handle requests to open a directory on a regular file. A local
attacker could use this to expose sensitive information (kernel memory).
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:
- x86 architecture;
- ATM drivers;
- Device frequency scaling framework;
- GPU drivers;
- Hardware monitoring drivers;
- VMware VMCI Driver;
- MTD block device drivers;
- Network drivers;
- Device tree and open firmware driver;
- SCSI subsystem;
- USB Serial drivers;
- BTRFS file system;
- File systems infrastructure;
- F2FS file system;
- JFS file system;
- NILFS2 file system;
- Netfilter;
- Memory management;
- Ethernet bridge;
- IPv6 networking;
- Logical Link layer;
- MAC80211 subsystem;
- NFC subsystem;
- Network traffic control;

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.
