Ubuntu 0090-1: Linux kernel vulnerability | LinuxSecurity.com
Linux kernel vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

-   Ubuntu 20.04 LTS
-   Ubuntu 18.04 LTS
-   Ubuntu 22.04 LTS

Summary

Several security issues were fixed in the kernel.

Software Description

-   linux - Linux kernel
-   linux-aws - Linux kernel for Amazon Web Services (AWS) systems
-   linux-azure - Linux kernel for Microsoft Azure Cloud systems
-   linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
-   linux-gke - Linux kernel for Google Container Engine (GKE) systems
-   linux-gkeop - Linux kernel for Google Container Engine (GKE) systems
-   linux-ibm - Linux kernel for IBM cloud systems

Details

David Bouman discovered that the netfilter subsystem in the Linux kernel
did not properly validate passed user register indices. A local attacker
could use this to cause a denial of service or possibly execute
arbitrary code. (CVE-2022-1015)

David Bouman and Billy Jheng Bing Jhong discovered that a race condition
existed in the io_uring subsystem in the Linux kernel, 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-2022-2602)

Sönke Huster discovered that an integer overflow vulnerability existed
in the WiFi driver stack in the Linux kernel, leading to a buffer
overflow. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-41674)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly perform reference counting in some situations, leading to a
use-after-free vulnerability. A physically proximate attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-42720)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly handle BSSID/SSID lists in some situations. A physically
proximate attacker could use this to cause a denial of service (infinite
loop). (CVE-2022-42721)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2022-42722)
