  3. CVE-2022-50169
In the Linux kernel, the following vulnerability has been resolved: wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi() The simple_write_to_buffer() function will succeed if even a single byte is initialized. However, we need to initialize the whole buffer to prevent information leaks. Just use memdup_user().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: wil6210: debugfs: corrección de fuga de información en wil_write_file_wmi(). La función simple_write_to_buffer() funcionará correctamente incluso si se inicializa un solo byte. Sin embargo, es necesario inicializar todo el búfer para evitar fugas de información. Simplemente use memdup_user().
