CVSS high 8.2
Firmware

Overview

Description
Null pointer dereference in the firmware for some Intel(R) AMT and Intel(R) Standard Manageability within Ring 0: Kernel may allow a denial of service. Network adversary with an unauthenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via network access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

  1. The Semtech LR11xx LoRa transceivers running early versions of firmware contains an information disclosure vulnerability in its firmware validation functionality. When a host issues a firmware validity check command via the SPI interface, the device decrypts the provided encrypted firmware package block-by-block to validate its integrity. However, the last decrypted firmware block remains uncleared in memory after the validation process completes. An attacker with access to the SPI interface can subsequently issue memory read commands to retrieve the decrypted firmware contents from this residual memory, effectively bypassing the firmware encryption protection mechanism. The attack requires physical access to the device's SPI interface.•CVE-2025-14858

  3. A flaw has been found in Tenda AC5 15.03.06.47. This vulnerability affects the function formQuickIndex of the file /goform/QuickIndex of the component POST Request Handler. This manipulation of the argument PPPOEPassword causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been published and may be used.•CVE-2026-4903
  4. A Missing Authentication for Critical Function vulnerability in Pharos Controls Mosaic Show Controller firmware version 2.15.3 could allow an unauthenticated attacker to bypass authentication and execute arbitrary commands with root privileges.•CVE-2026-2417
  5. A hardcoded cryptographic key within the configuration mechanism on TP-Link Archer NX200, NX210, NX500 and NX600 enables decryption and re-encryption of device configuration data. An authenticated attacker may decrypt configuration files, modify them, and re-encrypt them, affecting the confidentiality and integrity of device configuration data.•CVE-2025-15605
