Microsoft Pauses Windows Security Update KB5101650 After It Triggers Shutdowns and Overheating on Dell Laptops with Intel Processors
Microsoft has temporarily halted distribution of its July cumulative security update KB5101650 after the patch, which was designed to address 570 vulnerabilities across Windows, began causing serious stability and performance problems on select Dell laptops featuring Intel processors.
The update, released on 14 July as part of the regular monthly Patch Tuesday cycle, was also intended to introduce system restore-point functionality. Instead, affected users reported spontaneous shutdowns, reduced performance, excessive heat generation, and accelerated battery discharge.
Engineers identified the culprit as the Intel Innovation Platform Framework Processor Participant driver, a component responsible for regulating processor power consumption and cooling. When this driver malfunctioned, laptops could no longer maintain proper thermal and power balance, leading to the observed symptoms.
Microsoft had first detected driver-related warnings in the Device Manager after some users voluntarily installed the optional June update KB5095093. Because changes from optional updates are routinely merged into the subsequent mandatory release, the incompatibility spread to a wider audience in July.
The conflict was ultimately linked to the newly introduced Windows USB-C Connection Manager interface, added in June to improve USB-port handling, which proved incompatible with the Intel driver on certain Dell configurations.
Neither Microsoft nor Dell has published a list of affected models, making it impossible to determine the precise scale of exposure. Microsoft has confirmed that the update was blocked before it could install on incompatible devices, preventing any confirmed cases of permanent hardware damage.
The company stated it is collaborating with Intel and Dell on a resolution expected within days. For users whose systems are not impacted, Microsoft continues to advise immediate installation of the security update to benefit from protection against hundreds of known vulnerabilities.

Security Week 2644: Active Exploitation of PHP2Shell Vulnerabilities Confirmed
PHP developers released patches for two critical vulnerabilities collectively known as PHP2Shell on October 20, affecting PHP 8.2 through 8.5 as well as older branches. The flaws allow unauthenticated remote code execution on affected servers, which power approximately 70 percent of websites. Despite expectations of immediate exploitation, confirmed attacks with working exploits only began on October 25. CrowdStrike noted technical difficulties in weaponizing the issues in real-world environments. Only one-fifth of top Russian websites had applied the fixes by October 25. Additional incidents included compromised eMudhra certificates, a critical GitLab flaw, and a 16-year-old Broadcom router vulnerability.
Positive Technologies Offers Up to 500,000 Rubles for Bypassing PT Application Firewall
Positive Technologies has expanded its Standoff Bug Bounty program to include rewards for bypassing its web application firewalls. Researchers can earn between 150,000 and 500,000 rubles for demonstrating practical bypasses against PT Application Firewall PRO and PT Application Firewall Cloud. The program targets the core protective mechanisms, including traffic filtering, attack detection rules, and the management layer used by administrators. Submissions must include reproducible attack scenarios that show how malicious requests can pass through undetected, rather than relying on scanner reports or theoretical findings. Reward amounts vary by severity and confirmed business impact, with critical issues in the PRO version paying up to 500,000 rubles. The company plans to use validated findings to strengthen detection rules and improve overall product resilience.
Tailscale SSH Vulnerability Allows Root Access via Unix Socket Redirection
A researcher identified flaws in Tailscale that let an attacker with existing SSH access on one node escalate to root privileges and move laterally across the network. Erica Windisch of Cyberdione Labs demonstrated the issues in lab conditions against Tailscale 1.104.2 and Headscale 0.29.5. The core problem stems from privileged operations performed by the tailscaled process when handling Unix socket redirection, granting an ordinary SSH session access to root-only resources. The researcher used the technique to interact with Docker and run elevated commands, and showed that broad access policies allow automated lateral movement in under a second. Additional issues include denial-of-service conditions and bypasses of certain restrictions. Recommendations include reviewing SSH policies and disabling unnecessary socket redirection, noting that Headscale 0.29.5 lacks an independent way to turn the feature off.
Critical CVE-2026-111497 Out-of-Bounds Write Flaw in Google Brotli Decoder Impacts Broad Range of Environments
A severe vulnerability has been identified in the Google-developed Brotli decoder used for decompressing data in web communications and other applications. The flaw, tracked as CVE-2026-111497, allows out-of-bounds writes when processing specially crafted compressed data, potentially enabling arbitrary code execution, information disclosure, or denial of service. It carries a CVSS v4.0 base score of 9.2 and is rated Critical. Google has released patched versions 1.2.1, 1.1.1, and 1.0.10 of the library. Node.js incorporated the fix in its updates, while Microsoft issued an out-of-band patch for .NET on October 25, 2026, to address the issue. The vulnerability affects any environment relying on the Brotli C implementation for data decompression.
