USN-5318-1: Linux kernel vulnerabilities

9 March 2022

Several security issues were fixed in the Linux kernel.

Details

Nick Gregory discovered that the Linux kernel incorrectly handled network
offload functionality. A local attacker could use this to cause a denial of
service or possibly execute arbitrary code. (CVE-2022-25636)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
Giuffrida discovered that hardware mitigations added by ARM to their
processors to address Spectre-BTI were insufficient. A local attacker could
potentially use this to expose sensitive information. (CVE-2022-23960)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
Giuffrida discovered that hardware mitigations added by Intel to their
processors to address Spectre-BTI were insufficient. A local attacker could
potentially use this to expose sensitive information. (CVE-2022-0001,
CVE-2022-0002)

Update instructions

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

Ubuntu 20.04
Ubuntu 18.04

IMPORTANT: As part of this update, unprivileged eBPF is being
disabled by default, as it is the primary known means of exploiting
the Branch History Injection issues described above. It should be
noted that other mechanisms for exploiting the underlying issues may
be discovered. Also, this may cause issues for applications that
rely on the unprivileged eBPF functionality. Please see the knowledge
base article at https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/BHI
for more details.

After a standard system update you need to reboot your computer to make
all the necessary changes.
