USN-6231-1: Linux kernel (OEM) vulnerabilities
14 July 2023
Several security issues were fixed in the Linux kernel.
Releases
o Ubuntu 22.04 LTS
Packages
o linux-oem-6.1 – Linux kernel for OEM systems
Details
It was discovered that the XFS file system implementation in the Linux
kernel did not properly perform metadata validation when mounting certain
images. An attacker could use this to specially craft a file system image
that, when mounted, could cause a denial of service (system crash).
( CVE-2023-2124 )
It was discovered that the IP-VLAN network driver for the Linux kernel did
not properly initialize memory in some situations, leading to an out-of-
bounds write vulnerability. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. ( CVE-2023-3090 )
It was discovered that the DVB Core driver in the Linux kernel did not
properly handle locking events in certain situations. A local attacker
could use this to cause a denial of service (kernel deadlock).
( CVE-2023-31084 )
It was discovered that the Ricoh R5C592 MemoryStick card reader driver in
the Linux kernel contained a race condition during module unload, 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-2023-3141 )
Yang Lan discovered that the GFS2 file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious GFS2 image that, when
mounted and operated on, could cause a denial of service (system crash).
( CVE-2023-3212 )
Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 22.04
o linux-image-oem-22.04c – 6.1.0.1016.16
o linux-image-6.1.0-1016-oem – 6.1.0-1016.16
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.
