Ubuntu Security Notice USN-6725-2
April 16, 2024<\/p>\n
linux-aws, linux-aws-5.15 vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS
– Ubuntu 20.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems<\/p>\n
Details:<\/p>\n
Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate certain data structure fields when parsing lease
contexts, leading to an out-of-bounds read vulnerability. A remote attacker
could use this to cause a denial of service (system crash) or possibly
expose sensitive information. (CVE-2023-1194)<\/p>\n
Quentin Minster discovered that a race condition existed in the KSMBD
implementation in the Linux kernel, leading to a use-after-free
vulnerability. A remote attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2023-32254)<\/p>\n
It was discovered that a race condition existed in the KSMBD implementation
in the Linux kernel when handling session connections, leading to a use-
after-free vulnerability. A remote attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-32258)<\/p>\n
It was discovered that the KSMBD implementation in the Linux kernel did not
properly validate buffer sizes in certain operations, leading to an integer
underflow and out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38427)<\/p>\n
Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate SMB request protocol IDs, leading to a out-of-
bounds read vulnerability. A remote attacker could possibly use this to
cause a denial of service (system crash). (CVE-2023-38430)<\/p>\n
Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel
did not properly validate packet header sizes in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2023-38431)<\/p>\n
It was discovered that the KSMBD implementation in the Linux kernel did not
properly handle session setup requests, leading to an out-of-bounds read
vulnerability. A remote attacker could use this to expose sensitive
information. (CVE-2023-3867)<\/p>\n
Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)<\/p>\n
It was discovered that the IPv6 implementation of the Linux kernel did not
properly manage route cache memory usage. A remote attacker could use this
to cause a denial of service (memory exhaustion). (CVE-2023-52340)<\/p>\n
It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-52429, CVE-2024-23851)<\/p>\n
Yang Chaoming discovered that the KSMBD implementation in the Linux kernel
did not properly validate request buffer sizes, 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-2024-22705)<\/p>\n
Chenyuan Yang discovered that the btrfs file system in the Linux kernel did
not properly handle read operations on newly created subvolumes in certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-23850)<\/p>\n
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)<\/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-5.15.0-1057-aws 5.15.0-1057.63
linux-image-aws-lts-22.04 5.15.0.1057.58<\/p>\n
Ubuntu 20.04 LTS:
linux-image-5.15.0-1057-aws 5.15.0-1057.63~20.04.1
linux-image-aws 5.15.0.1057.63~20.04.1<\/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
