A use-after-free vulnerability in the Apache NuttX real-time operating system (RTOS) was disclosed, allowing attackers to crash systems and perform unintended filesystem operations. The flaw, tracked as CVE-2025-48769, affects the virtual file system (VFS) component and is present in NuttX versions 7.20 through 12.10.0. Attackers exploiting this vulnerability could trigger arbitrary buffer reallocations and write operations to freed heap memory, leading to system instability, especially in environments where network-exposed services with write access are enabled.
The Apache NuttX development team has released version 12.11.0 to address these issues, following a coordinated disclosure and rigorous review process. Security experts strongly recommend that organizations using affected versions upgrade immediately to mitigate the risk of exploitation. The vulnerabilities were discovered by Richard Jiayang Liu and the fixes were integrated after review by NuttX maintainers, highlighting the importance of timely patching in embedded and IoT environments relying on NuttX RTOS.

Several critical vulnerabilities have been disclosed affecting a range of widely used software frameworks and hardware platforms. Notable issues include a critical flaw in the Apache bRPC framework (CVE-2025-59789) that exposes high-performance systems to crash risks, a high-severity unauthenticated XXE vulnerability in GeoServer (CVE-2025-58360) enabling file theft and SSRF, and a critical SQL injection vulnerability in Devolutions Server (CVE-2025-13757) that allows authenticated attackers to steal all stored passwords. Additional disclosures include a proof-of-concept exploit for a Windows Administrator Protection elevation of privilege vulnerability (CVE-2025-60718), a critical boot process compromise in Snapdragon 8 Gen 3 and 5G modems (CVE-2025-47372), and a flaw in Apache Kvrocks that allows privilege escalation via the 'RESET' command. A separate high-severity vulnerability (CVE-2025-61618) was identified in Unisoc T8100/T9100/T8200/T8300 chipsets, affecting Android devices and allowing remote denial of service through improper input validation in the NR modem. These vulnerabilities collectively highlight the ongoing risk posed by both software and hardware flaws, with several enabling remote code execution, privilege escalation, or denial of service. Organizations using affected products should prioritize patching and mitigation efforts to reduce exposure to these critical threats.

NVIDIA issued security updates for multiple products across its AI and enterprise software stack, fixing vulnerabilities that could allow **remote code execution**, denial of service, privilege escalation, data tampering, and information disclosure. The most severe issue disclosed in its broader March advisories was `CVE-2025-33244` in **NVIDIA Apex**, a widely used PyTorch extension for mixed-precision and distributed training. High-severity flaws were also addressed in **Triton Inference Server**, **Megatron LM**, **NeMo Framework**, and **Model Optimizer**, with NVIDIA warning that exploitation could disrupt AI workloads, expose sensitive training data, or enable unauthorized access. Medium-severity issues were additionally listed in **VIRTIO-Net**, **SNAP4**, and **B300 MCU**. NVIDIA later released urgent fixes for **TensorRT-LLM** and **Isaac Launchable**, including TensorRT-LLM deserialization flaws in MPI server and RPC testing components that could lead to RCE, data manipulation, information disclosure, or service outages. It also patched a Linux issue in Isaac Launchable involving sensitive information sent in clear text, creating risks of privilege escalation and system disruption. NVIDIA advised customers to upgrade **TensorRT-LLM** to `1.2.1` or later, and said organizations running multi-GPU deployments should use: ```bash trtllm-llmapi-launch ``` to reduce network exposure. The company has also begun publishing PSIRT bulletins on GitHub in Markdown and CSAF formats to support automated vulnerability management and faster remediation.

A flaw tracked as **CVE-2026-43158** in the Linux kernel's **XFS** filesystem can let a local user trigger a denial of service by causing an assertion failure and filesystem shutdown. The bug affects XFS attribute leaf block handling during repeated `setxattr` operations: crafted extended attribute insertions can corrupt freemap accounting so that the entries array overlaps free space. The issue is classified as **CWE-617 Reachable Assertion**, carries a **CVSS v3 score of 7.0** from Red Hat, and traces back to code introduced in Linux `2.6.12`. The Linux kernel community published fixes across multiple stable branches, with maintainers advising organizations to update to current stable kernels rather than cherry-pick patches. Red Hat said no acceptable mitigation is available and shipped fixes through updated **RHEL** kernel packages and errata, including advisory **RHSA-2026:27735** for **RHEL 9.4 Update Services for SAP Solutions** and related variants. That advisory bundles **CVE-2026-43158** with other kernel vulnerabilities in components including **libceph**, **netfilter**, **SMB/CIFS**, **SCTP**, and **mac80211**, and requires affected systems to be rebooted after installation.
