– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
– linux-laptop: Linux kernel for Lenovo X13s ARM laptops
– linux-lowlatency: Linux low latency kernel
– linux-oracle: Linux kernel for Oracle Cloud systems
– linux-starfive: Linux kernel for StarFive processors
– linux-azure-6.5: Linux kernel for Microsoft Azure cloud systems
– linux-gcp-6.5: Linux kernel for Google Cloud Platform (GCP) systems
– linux-hwe-6.5: Linux hardware enablement (HWE) kernel
– linux-lowlatency-hwe-6.5: Linux low latency kernel
– linux-oem-6.5: Linux kernel for OEM systems
– linux-oracle-6.5: Linux kernel for Oracle Cloud systems
– linux-starfive-6.5: Linux kernel for StarFive processors<\/p>\n
Details:<\/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 Habana’s AI Processors driver in the Linux
kernel did not properly initialize certain data structures before passing
them to user space. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2023-50431)<\/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
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly validate certain SMB messages, 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-2023-6610)<\/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
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:
– Android drivers;
– Userspace I\/O drivers;
– F2FS file system;
– SMB network file system;
– Networking core;
(CVE-2023-52434, CVE-2023-52436, CVE-2023-52435, CVE-2023-52439,
CVE-2023-52438)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/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
