USN-6926-2: Linux kernel vulnerabilities

Read Time:1 Minute, 43 Second

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 a race condition existed in the Bluetooth subsystem
in the Linux kernel when modifying certain settings values through debugfs.
A privileged local attacker could use this to cause a denial of service.
(CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device
volume management subsystem did not properly validate logical eraseblock
sizes in certain situations. An attacker could possibly use this to cause a
denial of service (system crash). (CVE-2024-25739)

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.
(CVE-2024-25744)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– GPU drivers;
– HID subsystem;
– I2C subsystem;
– MTD block device drivers;
– Network drivers;
– TTY drivers;
– USB subsystem;
– File systems infrastructure;
– F2FS file system;
– SMB network file system;
– BPF subsystem;
– B.A.T.M.A.N. meshing protocol;
– Bluetooth subsystem;
– Networking core;
– IPv4 networking;
– IPv6 networking;
– Netfilter;
– Unix domain sockets;
– AppArmor security module;

USN-6941-1: Python vulnerability

Read Time:10 Second

It was discovered that the Python ipaddress module contained incorrect
information about which IP address ranges were considered “private” or
“globally reachable”. This could possibly result in applications applying
incorrect security policies.

Education in Secure Software Development

Read Time:28 Second

The Linux Foundation and OpenSSF released a report on the state of education in secure software development.

…many developers lack the essential knowledge and skills to effectively implement secure software development. Survey findings outlined in the report show nearly one-third of all professionals directly involved in development and deployment ­ system operations, software developers, committers, and maintainers ­ self-report feeling unfamiliar with secure software development practices. This is of particular concern as they are the ones at the forefront of creating and maintaining the code that runs a company’s applications and systems.
