CVSS high 8.7
Firmware

Overview

Description
Improper input validation in some UEFI firmware SMM module for the Intel(R) reference platforms may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (high) impacts.

  1. In the Linux kernel, the following vulnerability has been resolved: comedi: me_daq: Fix potential overrun of firmware buffer `me2600_xilinx_download()` loads the firmware that was requested by `request_firmware()`. It is possible for it to overrun the source buffer because it blindly trusts the file format. It reads a data stream length from the first 4 bytes into variable `file_length` and reads the data stream contents of length `file_length` from offset 16 onwards. Although it checks that the supplied firmware is at least 16 bytes long, it does not check that it is long enough to contain the data stream. Add a test to ensure that the supplied firmware is long enough to contain the header and the data stream. On failure, log an error and return `-EINVAL`.•CVE-2026-31748
  2. Penetration Testing engineers at Amazon have discovered a flaw where the camera system fails to properly handle data supplied in certain requests, causing a service disruption. The manufacturer has released patch firmware for the flaw, please refer to the manufacturer's report for details and workarounds.•CVE-2024-54011
  3. A vulnerability in SenseLive X3050’s remote management service allows firmware retrieval and update operations to be performed without authentication or authorization. The service accepts firmware-related requests from any reachable host and does not verify user privileges, integrity of uploaded images, or the authenticity of provided firmware.•CVE-2026-25775
  4. 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
