Background
The Linux kernel is the core component of the Linux operating system. It provides essential functionality for the system, including device drivers, process management, memory management, and networking. The Linux kernel is widely used in various distributions, including Debian. This report focuses on multiple vulnerabilities discovered in the Linux kernel.
Vulnerability Detail
The Linux kernel is affected by several vulnerabilities that could lead to privilege escalation, denial of service, or other impacts. These vulnerabilities include:
- CVE-2016-2188: The iowarrior device driver does not sufficiently validate USB descriptors, allowing a physically present user with a specially designed USB device to cause a denial of service.
- CVE-2016-9604: The keyring subsystem allows a process to set a special internal keyring as its session keyring, with an unknown security impact.
- CVE-2016-10200: A race condition in the L2TP implementation can corrupt its table of bound sockets, leading to denial of service or privilege escalation.
- CVE-2017-2647 / CVE-2017-6951: The keyring subsystem allows a process to search for dead keys, causing a null pointer dereference and denial of service.
- CVE-2017-2671: A race condition in the ping socket implementation can cause denial of service or privilege escalation.
- CVE-2017-5967: The /proc/timer_list file leaks information about all processes, potentially exposing sensitive information.
- CVE-2017-5970: A denial-of-service flaw in the IPv4 networking code can be triggered by a local or remote attacker.
- CVE-2017-7184: The net xfrm subsystem does not sufficiently validate replay state parameters, allowing a heap buffer overflow and privilege escalation.
- CVE-2017-7261: The vmwgfx driver does not sufficiently validate rendering surface parameters, leading to denial of service.
- CVE-2017-7273: The hid-cypress driver does not sufficiently validate HID reports, allowing a physically present user with a specially designed USB device to cause a denial of service.
- CVE-2017-7294: The vmwgfx driver does not sufficiently validate rendering surface parameters, leading to denial of service or privilege escalation.
- CVE-2017-7308: The packet socket implementation does not sufficiently validate buffer parameters, allowing privilege escalation.
- CVE-2017-7472: The keyring subsystem allows a thread to create new thread keyrings repeatedly, causing a memory leak and denial of service.
- CVE-2017-7616: Information leaks in the 32-bit big-endian compatibility implementations of set_mempolicy() and mbind().
- CVE-2017-7618: The cryptographic hash subsystem does not correctly handle submission of unaligned data, resulting in denial of service.
These vulnerabilities pose various risks, including crashes, privilege escalation, denial of service, and information leaks.
