23 May 2024
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux-aws-hwe - Linux kernel for Amazon Web Services (AWS-HWE) systems
Details
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
linux-image-4.15.0-1168-aws
-
4.15.0-1168.181~16.04.1
Available with Ubuntu Pro
-
linux-image-aws-hwe
-
4.15.0.1168.181~16.04.1
Available with Ubuntu Pro
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.
