CVE-2026-24747 high CVSS 8.8

Code Injection in Linuxfoundation (CVE-2026-24747)

Summary

Code injection in Linuxfoundation (CVE-2026-24747). Successful exploitation can lead to full system takeover. Exploitable via weights_only.

Original description

The description as published by the source.

Summary

A vulnerability in PyTorch's weights_only unpickler allows an attacker to craft a malicious checkpoint file (.pth) that, when loaded with torch.load(..., weights_only=True), can corrupt memory and potentially lead to arbitrary code execution.

Vulnerability Details

The weights_only=True unpickler failed to properly validate pickle opcodes and storage metadata, allowing:

  1. Heap memory corruption via SETITEM/SETITEMS opcodes applied to non-dictionary types
  2. Storage size mismatch between declared element count and actual data in the archive

Impact

An attacker who can convince a user to load a malicious checkpoint file may achieve arbitrary code execution in the context of the victim's process.

CVE-2026-24747 (Linuxfoundation) — CWE-94 / CVSS v3 8.8
Attack vector: remote (network-reachable) / unauthenticated
Attack surface: weights_only
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.

❓ What is the problem

Arbitrary code execution (CWE-94) exists in Linuxfoundation. Attackers reach the vulnerable code path via weights_only without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of Linuxfoundation. Attack surface: weights_only.

🔥 Severity

Severity: High (CVSS 8.8/10). Successful exploitation can lead to full system takeover.

🔧 How to fix

Update to the patched release per vendor advisory.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'Linuxfoundation' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'Linuxfoundation' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で Linuxfoundation を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
