CVE intelligence and bounded remediation

CVE-2023-2683 — Silabs Bluetooth Low Energy Software Development Kit security vulnerability

Medium CVSS 6.5

A memory leak in the EFR32 Bluetooth LE stack 5.1.0 through 5.1.1 allows an attacker to send an invalid pairing message and cause future legitimate connection attempts to fail. A reset of the device immediately clears the error.

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
