NVD description

VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and Fusion, the impact of this vulnerability is restricted to information disclosure.

    ⚡️ VMware just released a critical security update for ESXi hypervisor suite (VMSA-2026-0006). Two attack vectors: 1. Remote attack on vCenter – CVE-2026-59309: auth bypass via network access CVE-2026-59310: directory traversal RCE An exploit would allow control of entire ESXi infrastructure. 2. A VM-escapable set of two bugs – CVE-2026-59310: vmxnet3 OOBW CVE-2026-41703: core OOBR These are likely chainable to break out of VM and achieve code execution on hypervisor OS, as a privileged guest OS user. Diffing and exploiting (1) is straightforward and should be patched promptly.

    Post summary

    VMware announced a critical security update addressing several CVEs in ESXi, highlighting impact details and urging immediate patching, but no exploit code or confirmation of active exploitation is provided.

    🚨 Critical VMware vCenter Vulnerabilities — CVSS 9.8 Broadcom has issued VMSA-2026-0006.1 addressing multiple vulnerabilities across VMware vCenter, ESX, Workstation, Fusion and Cloud Foundation. * CVE-2026-59309 — Critical vCenter authentication bypass, CVSS 9.8. * An attacker with network access to vCenter may bypass authentication and gain unauthorized access. * CVE-2026-59310 — Critical vCenter directory traversal vulnerability, CVSS 9.8. * An attacker with network access may exploit it to execute arbitrary code on vCenter. * CVE-2026-47876 — Critical VMXNET3 out-of-bounds write, CVSS 9.3, potentially allowing a malicious VM administrator to execute code on the ESXi host. * Broadcom also patched CVE-2026-41703 and CVE-2026-41709. * Broadcom lists NO workaround for the critical vulnerabilities. Organizations should prioritize applying the available patches. 🔎 Analyst Note: vCenter represents a high-value management plane. Compromise can provide attackers with extensive visibility and control over virtualized infrastructure, making authentication bypass and remote code execution vulnerabilities particularly serious for enterprise environments.

    Patch

    Broadcomは、VMware製品群に影響する複数の脆弱性を修正するセキュリティアドバイザリ「VMSA-2026-0006」を公開した。vCenterの認証回避やESXでのVMエスケープなど重大な問題が含まれ、CVSS最大値は9.8となっている。 最も深刻なCVE-2026-59309は、vCenter ServerのDirectory Serviceに存在する認証回避で、ネットワーク経由で管理プレーンへ不正アクセスできる可能性がある。CVE-2026-59310はSyslogサーバーのディレクトリトラバーサルにより任意コード実行が可能となる脆弱性で、いずれもCVSS 9.8。ESXでは、VMXNET3仮想ネットワークアダプターの境界外書き込み(CVE-2026-47876、CVSS 9.3)により、VM内のローカル管理者権限からESXホスト上でコードを実行し、VMエスケープにつながる可能性がある。このほか、境界外読み取り(CVE-2026-41703)や監査ログ不備(CVE-2026-41709)も修正された。 影響を受けるのはvCenter Server、ESX、Workstation、Fusion、Cloud Foundation、vSphere Foundation、Telco Cloud製品などで、BroadcomはvCenter 9.1.0.0300、9.0.2.0100、8.0 U3kや、ESXiおよびWorkstation、Fusion向けの修正版を公開している。 https://cybersecuritynews.com/vmware-flaws-allow-authentication-bypass/

    Post summary

    Broadcom released the VMSA‑2026‑0006 advisory detailing nine high‑severity CVEs (all with CVSS 9.8 or 9.3), and provided patches for all affected VMware products.
