Microsoft says public sharing of Windows 11 vulnerability violates ‘best practices’

A security researcher known as Nightmare-Eclipse revealed a vulnerability in Windows 11, named YellowKey, which allows attackers to access BitLocker-encrypted drives through the Windows Recovery Environment. Microsoft acknowledged the vulnerability, assigned it the identifier CVE-2026-45585, and criticized the public sharing of its proof of concept. Currently, there is no patch available for the BitLocker bypass, but physical access to the device provides some protection. The vulnerability does not exist in Windows 10 due to differences in the Windows Recovery Environment. The attack requires a stolen Windows 11 laptop and a USB stick, and the vulnerable filesystems include NTFS, FAT32, and exFAT. Nightmare-Eclipse speculated that the bypass may function as a backdoor, while Microsoft referred to it as a "security feature bypass vulnerability."

CVE-2024-55638: Highly Critical Drupal Core Vulnerability Threatens PostgreSQL Sites with Remote Code Execution (RCE)

A critical vulnerability, CVE-2024-55638, has been identified in Drupal Core, affecting installations using PostgreSQL as their backend database. This vulnerability involves PHP Object Injection, which can lead to full Remote Code Execution (RCE) when combined with another deserialization flaw. It cannot be exploited independently but increases the risk for Drupal installations that use third-party modules or custom code that improperly employs the unserialize() function. The affected versions include Drupal Core 7.x prior to 7.102, 8.0.0 and above prior to 10.2.11, and 10.3.0 prior to 10.3.9, with patched versions being 7.102, 10.2.11, and 10.3.9. The vulnerability is particularly relevant for sites using PostgreSQL, and organizations are urged to upgrade to the patched versions and audit their code for unsafe unserialize() usage. Currently, there are no confirmed reports of exploitation in the wild, but the risk remains high due to insecure deserialization bugs in third-party modules. The EPSS score for this vulnerability is 9.93%, indicating a significant likelihood of exploitation in the near future.

Microsoft Defender Zero-Day Vulnerabilities RedSun and UnDefend Actively Exploited on Windows 10, 11, and Server (April 2026 CVE Analysis)

In April 2026, two zero-day vulnerabilities, RedSun and UnDefend, were discovered in Microsoft Defender, affecting Windows 10, Windows 11, and Windows Server platforms. These vulnerabilities allow attackers to escalate privileges to SYSTEM and bypass Defender’s protections. RedSun exploits a flaw in Defender's remediation process, enabling low-privileged users to overwrite critical system files. UnDefend allows attackers to disrupt Defender’s updates, keeping it outdated and ineffective. Both vulnerabilities are actively being exploited, with attackers leveraging them to gain persistent access and deploy ransomware. The primary targets are organizations using Windows systems with Defender enabled, particularly in sectors like finance, healthcare, and government. Mitigation strategies include applying updates for related vulnerabilities, monitoring for suspicious activities, and implementing additional security measures.

Nvidia tells users to update GPU drivers now or face possible attack — here’s what we know

NVIDIA has released an update to its GPU display drivers that addresses 14 vulnerabilities across its product lines, including GeForce, RTX, Quadro, Tesla, NVS, vGPU, and Cloud Gaming software. The most critical vulnerability is CVE‑2026‑24187, a high-severity use-after-free bug rated 8.8 out of 10, which could allow code execution, privilege escalation, data theft, or system crashes. Linux systems are vulnerable due to improper access to GPU resources at the kernel level, while Windows systems are at risk from a timing flaw. Two vulnerabilities in NVIDIA’s Unified Virtual Memory subsystem on Linux could lead to denial-of-service attacks without elevated permissions. The vGPU software also received patches for vulnerabilities in its virtual GPU manager component. Users can download the updated drivers from the NVIDIA Driver Downloads page or the NVIDIA Licensing Portal, with Windows users needing version 569.49 or newer and Linux users needing version 590.48.01. Users are advised to maintain their antivirus programs for enhanced security. NVIDIA thanked external security researchers for their responsible disclosure of these vulnerabilities.

PostgreSQL Flaws Expose Databases to Remote Code Execution and SQL Injection

PostgreSQL has released versions 18.4, 17.10, 16.14, 15.18, and 14.23 to address 11 security vulnerabilities and over 60 bugs. The vulnerabilities affect PostgreSQL versions 14 through 18 and include issues such as remote code execution, SQL injection, and denial-of-service risks. Specific vulnerabilities include: - CVE-2026-6472: Missing authorization in CREATE TYPE allows query hijacking. - CVE-2026-6473: Integer wraparound leads to out-of-bounds writes and server crashes. - CVE-2026-6474: Format string issue leaks server memory. - CVE-2026-6475: Symlink attack allows overwriting arbitrary files. - CVE-2026-6476: SQL injection allows execution of arbitrary SQL as superuser. - CVE-2026-6477: Memory buffer overwrite via libpq lo_* functions. - CVE-2026-6478: Timing attack exposes MD5-hashed passwords. - CVE-2026-6479: SSL/GSS recursion flaw allows denial-of-service. - CVE-2026-6575: Buffer over-read leaks memory data (PostgreSQL 18 only). - CVE-2026-6637: Refint module enables stack overflow and SQL injection, leading to possible RCE. - CVE-2026-6638: SQL injection in REFRESH PUBLICATION via table names. Organizations are advised to upgrade to the latest versions, avoid MD5 password authentication, restrict privileges, audit extensions, and monitor for abnormal activity. PostgreSQL 14 will reach its end-of-life on November 12, 2026.

Critical PostgreSQL Flaws Enable Code Execution and SQL Injection

On May 14, 2026, PostgreSQL released critical security updates for versions 18.4, 17.10, 16.14, 15.18, and 14.23, addressing 11 Common Vulnerabilities and Exposures (CVEs) related to stack buffer overflows, SQL injection, memory disclosure, and denial-of-service vulnerabilities. The most critical vulnerability, CVE-2026-6637, has a CVSS score of 8.8 and allows remote, unprivileged database users to execute arbitrary code. Other notable vulnerabilities include CVE-2026-6473, which affects memory allocation leading to potential memory corruption, and CVE-2026-6475, which allows overwriting sensitive OS-level files. Additional vulnerabilities include SQL injection flaws and authentication issues, with various CVSS scores ranging from 3.7 to 7.5. The updates can be implemented without a database dump, and PostgreSQL 14 will reach its end-of-life on November 12, 2026.

PoC Exploit Released for 20-Year Old PostgreSQL RCE Vulnerability

A proof-of-concept exploit has been developed for CVE-2026-2005, a remote code execution vulnerability in the pgcrypto extension of PostgreSQL. This vulnerability, stemming from legacy code, allows attackers to trigger a heap-based buffer overflow through specially crafted PGP messages, enabling arbitrary memory read and write operations. Successful exploitation can escalate privileges to PostgreSQL superuser status and execute commands on the operating system. The exploit targets PostgreSQL instances compiled from a specific vulnerable commit and circumvents protections like Address Space Layout Randomization (ASLR). It involves corrupting heap memory structures, leading to a controlled pointer leak that reveals the heap layout. Security researcher Varik Matevosyan has published the PoC on GitHub, demonstrating the exploitation process. The exploit requires a compatible PostgreSQL binary and utilizes Python-based tools for interaction. Organizations are advised to review their PostgreSQL deployments, disable unnecessary extensions, and apply security updates to mitigate risks.
