USN-5692-1: Linux kernel vulnerabilities

Publication date

19 October 2022

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

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)

could use this to cause a denial of service (system crash) or possibly

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)

Update instructions

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

Learn more about how to get the fixes.

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.

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