USN-6896-4: Linux kernel vulnerabilities

Recent discoveries have highlighted multiple vulnerabilities within the Linux kernel, posing significant risks to systems globally. This comprehensive overview details these vulnerabilities, their potential impacts, and how LinuxPatch provides crucial patches and updates to protect your infrastructure.

Vulnerability Overview

The Linux kernel, which forms the core of numerous operating systems and devices, has been found susceptible to a variety of security threats across different modules. These vulnerabilities range from race conditions and null pointer dereferences to integer overflows, each potentially allowing for denial of service attacks or unauthorized code execution.

Highlighted Vulnerabilities

Here's a closer look at some of the critical issues:

  • CVE-2023-6270: A race condition in the Linux kernel's ATA over Ethernet (AoE) driver can lead to a use-after-free scenario, possibly allowing attackers to execute arbitrary code or crash the system.
  • CVE-2023-7042: Incorrect validation of data structures by the Atheros 802.11ac wireless driver could lead to a null pointer dereference, creating a risk of denial of service.
  • CVE-2024-22099: The Bluetooth RFCOMM protocol driver is vulnerable to another race condition, potentially resulting in system crashes from null pointer dereferences.
  • CVE-2024-23307: A race condition in the Linux kernel's software RAID driver can lead to an integer overflow, a privileged attacker might exploit this to crash the system or perform unauthorized actions.
  • CVE-2024-24857 to CVE-2024-24859: These CVEs describe vulnerabilities in the Bluetooth subsystem which could lead to system instability due to improper handling of race conditions in kernel settings via debugfs.

System Impact and Mitigation

The extent and nature of these vulnerabilities can affect system stability, data security, and operational integrity across various deployment environments from personal computers to large servers. Prompt patching and application of updates are critical for protection.
