USN-6681-4: Linux kernel (AWS) vulnerabilities

Read Time:1 Minute, 48 Second

Wenqing Liu discovered that the f2fs file system implementation in the
Linux kernel did not properly validate inode types while performing garbage
collection. An attacker could use this to construct a malicious f2fs image
that, when mounted and operated on, could cause a denial of service (system
crash). (CVE-2021-44879)

It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the
Linux kernel did not properly handle certain error conditions during device
registration. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2023-22995)

Bien Pham discovered that the netfiler subsystem in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local user could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-4244)

It was discovered that a race condition existed in the Bluetooth subsystem
of 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-2023-51779)

It was discovered that a race condition existed in the ATM (Asynchronous
Transfer Mode) subsystem of 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-2023-51780)

It was discovered that a race condition existed in the Rose X.25 protocol
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-2023-51782)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel
did not properly handle connect command payloads in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to expose sensitive information (kernel memory). (CVE-2023-6121)

It was discovered that the VirtIO subsystem in the Linux kernel did not
properly initialize memory in some situations. A local attacker could use
this to possibly expose sensitive information (kernel memory).
(CVE-2024-0340)

Multiple Vulnerabilities in Mozilla Products Could Allow for Arbitrary Code Execution

Read Time:36 Second

Multiple vulnerabilities have been discovered in Mozilla products, the most severe of which could allow for arbitrary code execution.

Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Mozilla Thunderbird is an email client.

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

USN-6686-3: Linux kernel (Oracle) vulnerabilities

Read Time:1 Minute, 57 Second

It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the
Linux kernel did not properly handle certain error conditions during device
registration. A local attacker could possibly use this to cause a denial of
service (system crash). (CVE-2023-22995)

It was discovered that a race condition existed in the Cypress touchscreen
driver in the Linux kernel during device removal, 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-2023-4134)

黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-46343)

It was discovered that the io_uring subsystem in the Linux kernel contained
a race condition, leading to a null pointer dereference vulnerability. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-46862)

It was discovered that a race condition existed in the Bluetooth subsystem
of 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-2023-51779)

It was discovered that a race condition existed in the Rose X.25 protocol
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-2023-51782)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel
did not properly handle connect command payloads in certain situations,
leading to an out-of-bounds read vulnerability. A remote attacker could use
this to expose sensitive information (kernel memory). (CVE-2023-6121)

It was discovered that the VirtIO subsystem in the Linux kernel did not
properly initialize memory in some situations. A local attacker could use
this to possibly expose sensitive information (kernel memory).
(CVE-2024-0340)

Dan Carpenter discovered that the netfilter subsystem in the Linux kernel
did not store data in properly sized memory locations. A local user could
use this to cause a denial of service (system crash). (CVE-2024-0607)

Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and
Shweta Shinde discovered that the Confidential Computing framework in the
Linux kernel for x86 platforms did not properly handle 32-bit emulation on
TDX and SEV. An attacker with access to the VMM could use this to cause a
denial of service (guest crash) or possibly execute arbitrary code.
