Descrição técnica

Moby's overlay network driver does not restore the iptables rules for encrypted overlay networks after firewalld deletes them. Unlike other Docker Engine networking components, the overlay driver does not handle firewalld reload or start signals over D-Bus. The missing rules cause outgoing VXLAN datagrams to bypass IPsec encryption and remove the protection against incoming cleartext VXLAN traffic. The condition is not logged by dockerd and persists until the encrypted network's last local endpoint is removed and another is added, or dockerd is restarted. Each further firewalld event repeats the condition.

——0Protection mechanism failure for some BigDL before version 2.4.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.5h CVE-2026-40704—

——7ZcashFoundation Zebra from 4.5.0 before 7.0.0 contains a protection mechanism failure that bans honest peers by scoring mempool lock-time rejections at the ban threshold. Attackers can broadcast transactions locked until the current height right after each block, causing lagging nodes to ban honest relaying peers for 24 hours or until restart.3d CVE-2025-550025.5 MÉD

——3JupyterLab Desktop is the cross-platform desktop application for JupyterLab. Prior to 4.6.2-1, JupyterLab Desktop for macOS shipped with Electron's RunAsNode fuse enabled, allowing ELECTRON_RUN_AS_NODE to execute arbitrary Node.js code in the application process. An attacker who can already execute code as the current user can therefore run code in JupyterLab Desktop's context and inherit TCC permissions previously granted to the application, including access to protected Documents, Desktop, or Downloads folders without another macOS prompt. Exploitation requires existing local code execution and prior TCC grants; it does not provide initial or remote code execution. Windows and Linux are not affected. This vulnerability is fixed in 4.6.2-1.1d
