Overview

Several security issues were fixed in the Linux kernel.

Details

It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the HugeTLB file system component of the Linux
Kernel contained a NULL pointer dereference vulnerability. A privileged
attacker could possibly use this to to cause a denial of service.
(CVE-2024-0841)

It was discovered that the Open vSwitch implementation in the Linux kernel
could overflow its stack during recursive action operations under certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-1151)

Gui-Dong Han discovered that the software RAID driver in the Linux kernel
contained a race condition, leading to an integer overflow vulnerability. A
privileged attacker could possibly use this to cause a denial of service
(system crash). (CVE-2024-23307)

Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in
the Linux kernel contained a race condition, leading to an integer overflow
vulnerability. An attacker could possibly use this to cause a denial of
service (system crash). (CVE-2024-24861)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

The problem can be corrected by updating your system to the following package versions:
