Key Findings: A critical vulnerability has been discovered in the Linux kernel's x86 page fault handling mechanism, existing since 2020. The flaw was caused by inconsistent disabling of hardware interrupts, leading to potential catastrophic scenarios. The vulnerability was not limited to user-space address errors, but involved a more complex interplay between address ranges and execution context. The remediation required a fundamental shift in approach, moving away from selec

Key Findings Researchers from Google Project Zero have discovered a comprehensive "zero-click" exploit chain targeting the Google Pixel 9 smartphone. The exploit chain spans from remote code execution during media decoding to the ultimate compromise of the kernel. The vulnerabilities were patched in the security updates released on January 5, 2026. Background The pivotal shift in recent years lies in the propensity of "intelligent" smartphone features to preemptively analyze

Key Findings HPE Networking has released critical software patches for vulnerabilities in its Instant On series of access points and routers. The flaws include a high-severity Denial-of-Service (DoS) vulnerability (CVE-2025-37166) that can crash devices, and an information exposure issue (CVE-2025-37165) that could leak network configuration details. The update also addresses legacy kernel-level vulnerabilities (CVE-2023-52340, CVE-2022-48839) that could lead to DoS and memor

Key Findings HoneyMyte, also known as Mustang Panda or Bronze President, has deployed a sophisticated kernel-mode rootkit to infiltrate government networks in Southeast and East Asia. The rootkit, named ProjectConfiguration.sys, is signed with a stolen digital certificate to bypass security checks. The rootkit acts as a "bodyguard" for HoneyMyte's malware, including the group's signature backdoor ToneShell, by manipulating driver loading order to blind security software like

Key Findings: A use-after-free (UAF) vulnerability in the Linux kernel's io_uring subsystem can be exploited to bypass the BPF verifier and achieve container escape. The flaw, tracked as CVE-2025-40364, allows attackers to manipulate the BPF verifier and gain arbitrary kernel code execution. Proof-of-concept (PoC) exploits have been publicly released, demonstrating the feasibility of the attack. Background The Linux kernel's io_uring subsystem is a high-performance I/O interf

Key Findings: A newly discovered vulnerability in the Windows Kernel, tracked as CVE-2025-62215, allows local privilege escalation. The flaw, present in all supported versions of Windows, enables a low-privileged user or process to elevate their permissions to gain SYSTEM-level access. Proof-of-concept (PoC) exploits have been publicly released, demonstrating the ability to achieve arbitrary code execution with SYSTEM privileges. The vulnerability is considered high-severity,
