Vulnerability Data

A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets…

to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.

MITRE ATT&CK Enterprise Techniques

T1001 Data Obfuscation Command And Control
Adversaries may obfuscate command and control traffic to make it more difficult to detect.
T1001.002 Steganography Command And Control
Adversaries may use steganographic techniques to hide command and control traffic to make detection efforts more difficult.
T1003.002 Security Account Manager Credential Access
Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database either through in-memory techniques or through the Windows Registry where the SAM database is stored.
T1003.008 /etc/passwd and /etc/shadow Credential Access
Adversaries may attempt to dump the contents of <code>/etc/passwd</code> and <code>/etc/shadow</code> to enable offline password cracking.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

A.8.15 Logging partial match
finds

Logging may detect excessive consumption but does not stop the loop.

finds

Monitoring can alert on resource abuse but does not eliminate the coding flaw.

blocks

Secure SDLC processes can catch the weakness during reviews but do not inherently prevent it.

prevents

Secure coding standards explicitly forbid resource-consuming loops.
