Ubuntu Security Notice USN-7008-1
September 13, 2024<\/p>\n
linux-lowlatency-hwe-6.8 vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-lowlatency-hwe-6.8: Linux low latency kernel<\/p>\n
Details:<\/p>\n
Chenyuan Yang discovered that the CEC driver driver in the Linux kernel
contained 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-2024-23848)<\/p>\n
It was discovered that the JFS file system contained an out-of-bounds read
vulnerability when printing xattr debug information. A local attacker could
use this to cause a denial of service (system crash). (CVE-2024-40902)<\/p>\n
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 22.04 LTS
linux-image-6.8.0-44-lowlatency 6.8.0-44.44.1~22.04.1
linux-image-6.8.0-44-lowlatency-64k 6.8.0-44.44.1~22.04.1
linux-image-lowlatency-64k-hwe-22.04 6.8.0-44.44.1~22.04.1
linux-image-lowlatency-hwe-22.04 6.8.0-44.44.1~22.04.1<\/p>\n
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
