- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-starfive: Linux kernel for StarFive processors
- linux-aws-6.5: Linux kernel for Amazon Web Services (AWS) systems
- 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-nvidia-6.5: Linux kernel for NVIDIA systems
- 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
Details:
Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux
kernel contained a race condition during device removal, leading to a use-
after-free vulnerability. A physically proximate attacker could possibly
use this to cause a denial of service (system crash). (CVE-2023-47233)
Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)
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:
- Hardware random number generator core;
- Ext4 file system;
- JFS file system;
- Bluetooth subsystem;
- Networking core;
- IPv4 networking;
- Logical Link layer;
- Netlink;
- Tomoyo security module;
(CVE-2024-26704, CVE-2023-52615, CVE-2024-26805, CVE-2023-52604,
CVE-2024-26614, CVE-2023-52602, CVE-2024-26635, CVE-2024-26622,
CVE-2023-52601, CVE-2024-26801)

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.
