CVE-2025-1816 — A vulnerability classified as problematic has been found in FFmpeg up to 6e26f57f672b05e7b8b052007a83aef99dc81ccb

Medium CVSS 5.3

A vulnerability classified as problematic has been found in FFmpeg up to 6e26f57f672b05e7b8b052007a83aef99dc81ccb. This affects the function audio_element_obu of the file libavformat/iamf_parse.c of the component IAMF File Handler. The manipulation of the argument num_parameters leads to memory leak. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of the patch is 0526535cd58444dd264e810b2f3348b4d96cff3b.

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.
