========================================================================== Ubuntu Security Notice USN-5002-1 June 23, 2021
linux-hwe, linux-gke-5.3, linux-raspi2-5.3 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
Summary:
The system could be made to run programs as an administrator.
Software Description: - linux-gke-5.3: Linux kernel for Google Container Engine (GKE) systems - linux-hwe: Linux hardware enablement (HWE) kernel - linux-raspi2-5.3: Linux kernel for Raspberry Pi (V8) systems
Details:
Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: linux-image-5.3.0-1041-raspi2 5.3.0-1041.43 linux-image-5.3.0-1044-gke 5.3.0-1044.47 linux-image-5.3.0-75-generic 5.3.0-75.71 linux-image-5.3.0-75-lowlatency 5.3.0-75.71 linux-image-gke-5.3 5.3.0.1044.27 linux-image-gkeop-5.3 5.3.0.75.132 linux-image-raspi2-hwe-18.04 5.3.0.1041.30
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.
