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. ( CVE-2021-3609 )

Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel
did not properly enforce limits for pointer operations. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. ( CVE-2021-33200 )

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did
not properly clear received fragments from memory in some situations. A
physically proximate attacker could possibly use this issue to inject
packets or expose sensitive information. ( CVE-2020-24586 )

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled encrypted fragments. A physically proximate attacker
could possibly use this issue to decrypt fragments. ( CVE-2020-24587 )

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled certain malformed frames. If a user were tricked into
connecting to a malicious server, a physically proximate attacker could use
this issue to inject packets. ( CVE-2020-24588 )

Kiyin () discovered that the NFC LLCP protocol implementation in the
Linux kernel contained a reference counting error. A local attacker could
use this to cause a denial of service (system crash). ( CVE-2020-25670 )

Kiyin () discovered that the NFC LLCP protocol implementation in the
Linux kernel did not properly deallocate memory in certain error
situations. A local attacker could use this to cause a denial of service
(memory exhaustion). ( CVE-2020-25671 , CVE-2020-25672 )

Kiyin () discovered that the NFC LLCP protocol implementation in the
Linux kernel did not properly handle error conditions in some situations,
leading to an infinite loop. A local attacker could use this to cause a
denial of service. ( CVE-2020-25673 )

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled EAPOL frames from unauthenticated senders. A physically
proximate attacker could inject malicious packets to cause a denial of
service (system crash). ( CVE-2020-26139 )

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did
not properly verify certain fragmented frames. A physically proximate
attacker could possibly use this issue to inject or decrypt packets.
( CVE-2020-26141 )

Mathy Vanhoef discovered that the in the Linux kernel’s WiFi implementation
leading to accepting plaintext fragments. A physically proximate attacker
could use this issue to inject packets. ( CVE-2020-26145 )

Mathy Vanhoef discovered that the the Linux kernel’s WiFi implementation
leading to reassembling mixed encrypted and plaintext fragments. A
physically proximate attacker could possibly use this issue to inject
packets or exfiltrate selected fragments. ( CVE-2020-26147 )

Or Cohen discovered that the SCTP implementation in the Linux kernel
contained a race condition in some situations, leading to a use-after-free
condition. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. ( CVE-2021-23133 )

Piotr Krysiuk and Benedict Schlueter discovered that the eBPF
implementation in the Linux kernel performed out of bounds speculation on
pointer arithmetic. A local attacker could use this to expose sensitive
information. ( CVE-2021-29155 )

Manfred Paul discovered that the extended Berkeley Packet Filter (eBPF)
implementation in the Linux kernel contained an out-of-bounds
vulnerability. A local attacker could use this issue to execute arbitrary
code. ( CVE-2021-31440 )

Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel
did not properly prevent speculative loads in certain situations. A local
attacker could use this to expose sensitive information (kernel memory).
( CVE-2021-31829 )

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.

Details

Or Cohen and Nadav Markus discovered a use-after-free vulnerability in the
nfc implementation in the Linux kernel. A privileged local attacker could
use this issue to cause a denial of service (system crash) or possibly
execute arbitrary code. ( CVE-2021-23134 )

It was discovered that a race condition in the kernel Bluetooth subsystem
can lead to use-after-free of slab objects. An attacker could use this
issue to possibly execute arbitrary code. ( CVE-2021-32399 )

It was discovered that a use-after-free existed in the Bluetooth HCI driver
of the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. ( CVE-2021-33034 )

It was discovered that an out-of-bounds (OOB) memory access flaw in the
f2fs module of the Linux kernel. A local attacker could use this issue to
cause a denial of service (system crash). ( CVE-2021-3506 )

USN-5003-1: Linux kernel vulnerabilities
23 June 2021

Several security issues were fixed in the Linux kernel.
Releases

o Ubuntu 18.04 LTS
o Ubuntu 16.04 ESM
o Ubuntu 14.04 ESM

Packages

o linux – Linux kernel
o linux-aws – Linux kernel for Amazon Web Services (AWS) systems
o linux-aws-hwe – Linux kernel for Amazon Web Services (AWS-HWE) systems
o linux-azure – Linux kernel for Microsoft Azure Cloud systems
o linux-azure-4.15 – Linux kernel for Microsoft Azure Cloud systems
o linux-dell300x – Linux kernel for Dell 300x platforms
o linux-gcp – Linux kernel for Google Cloud Platform (GCP) systems
o linux-gcp-4.15 – Linux kernel for Google Cloud Platform (GCP) systems
o linux-hwe – Linux hardware enablement (HWE) kernel
o linux-oracle – Linux kernel for Oracle Cloud systems
o linux-raspi2 – Linux kernel for Raspberry Pi (V8) systems
o linux-snapdragon – Linux kernel for Qualcomm Snapdragon processors

Details

It was discovered that the eBPF implementation in the Linux kernel did not
properly track bounds information for 32 bit registers when performing div
and mod operations. A local attacker could use this to possibly execute
arbitrary code. ( CVE-2021-3600 )

Update instructions

The problem can be corrected by updating your system to the following package
versions:
