CVE-2026-92961: Allocation of Resources Without Limits or Throttling in patriksimek vm2
CVE-2026-92961 is a high-severity vulnerability in patriksimek vm2 prior to version 3.11.6. The vulnerability arises because vm2 fails to enforce the bufferAllocLimit on ArrayBuffer, SharedArrayBuffer, and TypedArray constructors. This allows attackers to allocate arbitrary host memory, potentially exhausting the host process memory and causing out-of-memory conditions.
AI Analysis
Technical Summary
The vulnerability CVE-2026-92961 affects patriksimek vm2 versions before 3.11.6. The product does not enforce the bufferAllocLimit on certain JavaScript buffer constructors (ArrayBuffer, SharedArrayBuffer, TypedArray), enabling attackers to bypass memory allocation caps. By exploiting this, attackers can allocate excessive host memory, leading to exhaustion of process memory and triggering out-of-memory errors. The CVSS 4.0 score is 8.7, indicating high severity with network attack vector, no privileges or user interaction required, and high impact on availability.
Potential Impact
Successful exploitation allows attackers to allocate arbitrary amounts of host memory, bypassing intended allocation limits. This can exhaust the host process memory, causing out-of-memory conditions that may disrupt service availability or cause crashes.
Mitigation Recommendations
A fix is available in patriksimek vm2 version 3.11.6. Users should upgrade to version 3.11.6 or later to remediate this vulnerability. No additional mitigation steps are indicated.
