========================================================================== Ubuntu Security Notice USN-6680-2 March 08, 2024
linux-azure, linux-azure-6.5, linux-hwe-6.5 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 23.10 - Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-azure-6.5: Linux kernel for Microsoft Azure cloud systems - linux-hwe-6.5: Linux hardware enablement (HWE) kernel
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 23.10: linux-image-6.5.0-1016-azure 6.5.0-1016.16 linux-image-6.5.0-1016-azure-fde 6.5.0-1016.16 linux-image-azure 6.5.0.1016.18 linux-image-azure-fde 6.5.0.1016.18
Ubuntu 22.04 LTS: linux-image-6.5.0-1016-azure 6.5.0-1016.16~22.04.1 linux-image-6.5.0-1016-azure-fde 6.5.0-1016.16~22.04.1 linux-image-6.5.0-25-generic 6.5.0-25.25~22.04.1 linux-image-6.5.0-25-generic-64k 6.5.0-25.25~22.04.1 linux-image-azure 6.5.0.1016.16~22.04.1 linux-image-azure-fde 6.5.0.1016.16~22.04.1 linux-image-generic-64k-hwe-22.04 6.5.0.25.25~22.04.12 linux-image-generic-hwe-22.04 6.5.0.25.25~22.04.12 linux-image-virtual-hwe-22.04 6.5.0.25.25~22.04.12
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.
