[dhcp: unbounded tx growth with unidirectional traffic]
AnalysisAI
Unbounded transmit (tx) buffer growth in the Linux kernel's DHCP subsystem can exhaust system memory when traffic is unidirectional. The defect allows the kernel's DHCP-related transmit path to accumulate resources indefinitely - packets or descriptors are enqueued without corresponding release when bidirectional flow acknowledgment is absent. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to generate DHCP traffic (UDP port 67/68) toward the target system, or to create network conditions where the kernel's DHCP transmit path operates unidirectionally without reciprocal traffic to trigger cleanup. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | With no CVSS vector, EPSS score, or KEV status provided, risk quantification relies on structural analysis of the vulnerability class. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Ubuntu-provided kernel patch addressing CVE-2026-57224 via the standard Ubuntu security update channel (apt-get update && apt-get upgrade or unattended-upgrades). … Detailed patch versions, workarounds, and compensating controls in full report. |
