Details
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)
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:
- Block layer subsystem;
- Networking core;
(CVE-2024-56672, CVE-2024-56658)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 24.10
-
linux-image-6.11.0-1010-azure
-
6.11.0-1010.10
-
linux-image-6.11.0-1010-azure-fde
-
6.11.0-1010.10
-
linux-image-azure
-
6.11.0-1010.10
-
linux-image-azure-fde
-
6.11.0-1010.10
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.
