USN-6653-1: Linux kernel vulnerabilities

Publication date

23 February 2024

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

It was discovered that a race condition existed in the ATM (Asynchronous
Transfer Mode) subsystem of the Linux kernel, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-51780)

It was discovered that a race condition existed in the AppleTalk networking
subsystem of the Linux kernel, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2023-51781)

Zhenghan Wang discovered that the generic ID allocator implementation in
the Linux kernel did not properly check for null bitmap when releasing IDs.
A local attacker could use this to cause a denial of service (system
crash). (CVE-2023-6915)

Robert Morris discovered that the CIFS network file system implementation
in the Linux kernel did not properly validate certain server commands
fields, leading to an out-of-bounds read vulnerability. An attacker could
use this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2024-0565)

Jann Horn discovered that the TLS subsystem in the Linux kernel did not
properly handle spliced messages, leading to an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2024-0646)

Update instructions

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

Learn more about how to get the fixes.

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.

The problem can be corrected by updating your system to the following package versions:
