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…

Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Runtime monitoring can detect excessive resource use from loops as an adverse event.
Capacity monitoring and resource management directly limit impact of runaway consumption.
Secure SDLC practices can prevent introduction of unbounded loops during development.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Monitoring can alert on resource abuse but does not eliminate the coding flaw.
Security testing can discover the defect but does not remove it from production code.
Redundancy can absorb some resource spikes but does not prevent the loop defect.
Logging may detect excessive consumption but does not stop the loop.
Secure SDLC processes can catch the weakness during reviews but do not inherently prevent it.
Secure coding standards explicitly forbid resource-consuming loops.
