to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-32233)

Gwangun Jung discovered that the Quick Fair Queueing scheduler
implementation in the Linux kernel contained an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-31436)

Reima Ishii discovered that the nested KVM implementation for Intel x86
processors in the Linux kernel did not properly validate control registers
in certain situations. An attacker in a guest VM could use this to cause a
denial of service (guest crash). (CVE-2023-30456)

It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform data buffer size validation in some
situations. A physically proximate attacker could use this to craft a
malicious USB device that when inserted, could cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-1380)

Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu
Linux kernel contained a race condition when handling inode locking in some
situations. A local attacker could use this to cause a denial of service
(kernel deadlock). (CVE-2023-2612)

Title: USN-6128-1: CUPS vulnerability
URL: https://ubuntu.com/security/notices/USN-6128-1
Priorities: medium
Description:
It was discovered that CUPS incorrectly handled logging. A remote attacker
could use this issue to cause CUPS to crash, resulting in a denial of
service, or possibly execute arbitrary code.

Title: USN-6165-1: GLib vulnerabilities
URL: https://ubuntu.com/security/notices/USN-6165-1
Priorities: medium,low
Description:
It was discovered that GLib incorrectly handled non-normal GVariants. An
attacker could use this issue to cause GLib to crash, resulting in a denial
of service, or perform other unknown attacks.

Title: USN-6147-1: SpiderMonkey vulnerability
URL: https://ubuntu.com/security/notices/USN-6147-1
Priorities: medium
Description:
Several security issues were discovered in the SpiderMonkey JavaScript
library. If a user were tricked into opening malicious JavaScript
applications or processing malformed data, a remote attacker could exploit
a variety of issues related to JavaScript security, including denial of
service attacks, and arbitrary code execution.
