9 verified briefings on Security Patch. Each story includes a plain-English summary, why it matters, and the concrete action engineering teams should take.
Multiple security vulnerabilities have been discovered in the Linux kernel, affecting its cryptographic API and packet sockets. A significant flaw, dubbed "Copy Fail," could allow a local attacker to escalate privileges or even escape a container, potentially leading to a full system compromise. An update has been released.
Security researchers discovered and patched a series of vulnerabilities, named 'Claw Chain', in the OpenClaw AI agent framework. These flaws could have allowed attackers to steal credentials, escalate privileges, and maintain persistent access within affected systems, posing a significant threat to deployments using the framework.
Ubuntu has released security updates for the Linux kernel on Xilinx ZynqMP systems. These patches address multiple vulnerabilities, including critical flaws in the OverlayFS implementation that could allow a local attacker to gain elevated privileges and compromise the security of affected devices.
Ubuntu has patched several Linux kernel vulnerabilities, including two in its OverlayFS file system. These flaws could allow a local attacker to bypass permission checks and gain elevated privileges, potentially leading to unauthorized system control. Users should update their systems immediately to mitigate the risk.
Drupal has announced an upcoming core security release for all supported branches, scheduled for May 20, 2026. The Drupal Security Team is urging site administrators to prepare for immediate updates, warning that exploits could be developed within hours or days of the patch's release.
Ubuntu has patched two vulnerabilities in the rsync utility. One flaw could allow a remote attacker to cause a denial of service, while another could let a local attacker overwrite files on systems with specific configurations. The issues affect recent versions of Ubuntu, including 22.04 and 24.04 LTS.
Ubuntu has released a security update for the Linux kernel, fixing several vulnerabilities. The most critical flaw, known as Copy Fail, could allow a local attacker to escalate privileges or escape from a container. The patch also addresses issues in various other kernel subsystems to prevent system compromise.
Microsoft's May Security Update for Windows 11 is failing to install on some devices. The issue is caused by insufficient free space on the EFI System Partition. This leaves affected systems vulnerable, as they do not receive the dozens of security patches included in the update.
A Windows vulnerability in the Cloud Filter driver, thought to be patched six years ago, is still exploitable. A security researcher has demonstrated a new method to exploit the flaw, allowing an attacker to gain full SYSTEM-level privileges on an affected machine.
