USN-5851-1: Linux kernel vulnerabilities

Read Time:2 Minute, 12 Second

It was discovered that a memory leak existed in the Unix domain socket
implementation of the Linux kernel. A local attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2022-3543)

It was discovered that the Bluetooth HCI implementation in the Linux kernel
did not properly deallocate memory in some situations. An attacker could
possibly use this cause a denial of service (memory exhaustion).
(CVE-2022-3619)

It was discovered that the hugetlb implementation in the Linux kernel
contained a race condition in some situations. A local attacker could use
this to cause a denial of service (system crash) or expose sensitive
information (kernel memory). (CVE-2022-3623)

It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform bounds checking 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 execute arbitrary code. (CVE-2022-3628)

It was discovered that a use-after-free vulnerability existed in the
Bluetooth stack in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3640)

It was discovered that a race condition existed in the SMSC UFX USB driver
implementation in the Linux kernel, 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-2022-41849)

It was discovered that a race condition existed in the Roccat HID driver 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-2022-41850)

Tamás Koczka discovered that the Bluetooth L2CAP implementation in the
Linux kernel did not properly initialize memory in some situations. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-42895)

Arnaud Gatignol, Quentin Minster, Florent Saudel and Guillaume Teissier
discovered that the KSMBD implementation in the Linux kernel did not
properly validate user-supplied data in some situations. An authenticated
attacker could use this to cause a denial of service (system crash), expose
sensitive information (kernel memory) or possibly execute arbitrary code.
(CVE-2022-47940)

It was discovered that a race condition existed in the qdisc implementation
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-2023-0590)

USN-5835-5: Nova vulnerability

Read Time:18 Second

USN-5835-3 fixed vulnerabilities in Nova. This update provides the
corresponding updates for Ubuntu 18.04 LTS.

Original advisory details:

Guillaume Espanel, Pierre Libeau, Arnaud Morin, and Damien Rannou
discovered that Nova incorrectly handled VMDK image processing. An
authenticated attacker could possibly supply a specially crafted VMDK flat
image and obtain arbitrary files from the server containing sensitive
information.
