USN-5517-1: Linux kernel (OEM) vulnerabilities
13 July 2022
Several security issues were fixed in the Linux kernel.
Releases
o Ubuntu 20.04 LTS
Packages
o linux-oem-5.14 - Linux kernel for OEM systems
Details
It was discovered that the Atheros ath9k wireless device driver in the
Linux kernel did not properly handle some error conditions, 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-2022-1679 )
It was discovered that the virtio RPMSG bus driver in the Linux kernel
contained a double-free vulnerability in certain error conditions. A local
attacker could possibly use this to cause a denial of service (system
crash). ( CVE-2022-34494 )
Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 20.04
o linux-image-oem-20.04c - 5.14.0.1045.41
o linux-image-oem-20.04b - 5.14.0.1045.41
o linux-image-oem-20.04d - 5.14.0.1045.41
o linux-image-oem-20.04 - 5.14.0.1045.41
o linux-image-5.14.0-1045-oem - 5.14.0-1045.51
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.
