  2. Vulnerabilities (CVE)
  3. CVE-2024-26927
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Add some bounds checking to firmware data Smatch complains about "head->full_size - head->header_size" can underflow. To some extent, we're always going to have to trust the firmware a bit. However, it's easy enough to add a check for negatives, and let's add a upper bounds check as well.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ASoC: SOF: agregue algunas comprobaciones de los límites a los datos del firmware. Smatch se queja de que "head->full_size - head->header_size" puede desbordarse. Hasta cierto punto, siempre vamos a tener que confiar un poco en el firmware. Sin embargo, es bastante fácil agregar una verificación de negativos y agreguemos también una verificación de los límites superiores.
