========================================================================== Ubuntu Security Notice USN-4413-1 July 02, 2020
linux-gke-5.0, linux-oem-osp1 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-gke-5.0: Linux kernel for Google Container Engine (GKE) systems - linux-oem-osp1: Linux kernel for OEM systems
Details:
Matthew Sheets discovered that the SELinux network label handling implementation in the Linux kernel could be coerced into de-referencing a NULL pointer. A remote attacker could use this to cause a denial of service (system crash). (CVE-2020-10711)
It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain error conditions correctly. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2020-12770)
It was discovered that the USB Gadget device driver in the Linux kernel did not validate arguments passed from configfs in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-13143)
Dmitry Vyukov discovered that the SELinux netlink security hook in the Linux kernel did not validate messages in some situations. A privileged attacker could use this to bypass SELinux netlink restrictions. (CVE-2020-10751)
It was discovered that the KVM implementation in the Linux kernel did not properly deallocate memory on initialization for some processors. A local attacker could possibly use this to cause a denial of service. (CVE-2020-12768)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: linux-image-5.0.0-1043-gke 5.0.0-1043.44 linux-image-5.0.0-1063-oem-osp1 5.0.0-1063.68 linux-image-gke-5.0 5.0.0.1043.28 linux-image-oem-osp1 5.0.0.1063.61
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.
