CVE-2025-21905

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-21905
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: limit printed string from FW file There's no guarantee here that the file is always with a NUL-termination, so reading the string may read beyond the end of the TLV. If that's the last TLV in the file, it can perhaps even read beyond the end of the file buffer. Fix that by limiting the print format to the size of the buffer we have.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: iwlwifi: limitar la cadena impresa del archivo FW. No se garantiza que el archivo siempre tenga una terminación NUL, por lo que al leer la cadena, se podría leer más allá del final del TLV. Si ese es el último TLV del archivo, es posible que incluso pueda leer más allá del final del búfer del archivo. Para solucionar esto, limite el formato de impresión al tamaño del búfer disponible.
