- linux-laptop: Linux kernel for Lenovo X13s ARM laptops
- linux-lowlatency: Linux low latency kernel
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-starfive: Linux kernel for StarFive processors
- linux-gcp-6.5: Linux kernel for Google Cloud Platform (GCP) systems
- linux-lowlatency-hwe-6.5: Linux low latency kernel
- linux-oem-6.5: Linux kernel for OEM systems
- linux-starfive-6.5: Linux kernel for StarFive processors
Details:
黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-46343)
It was discovered that a race condition existed in the Bluetooth 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-2023-51779)
It was discovered that a race condition existed in the Rose X.25 protocol
implementation in 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-2023-51782)
Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel
did not properly handle connect command payloads in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to expose sensitive information (kernel memory). (CVE-2023-6121)
Jann Horn discovered that the io_uring subsystem in the Linux kernel
contained an out-of-bounds access vulnerability. A local attacker could use
this to cause a denial of service (system crash). (CVE-2023-6560)
Dan Carpenter discovered that the netfilter subsystem in the Linux kernel
did not store data in properly sized memory locations. A local user could
use this to cause a denial of service (system crash). (CVE-2024-0607)
Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and
Shweta Shinde discovered that the Confidential Computing framework in the
Linux kernel for x86 platforms did not properly handle 32-bit emulation on
TDX and SEV. An attacker with access to the VMM could use this to cause a
denial of service (guest crash) or possibly execute arbitrary code.
(CVE-2024-25744)

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.
