Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: se corrige el error de desreferencia de puntero nulo en generate_encryptionkey. Si el cliente envía dos configuraciones de sesión con autenticación krb5 a ksmbd, podría producirse un error de desreferencia de puntero nulo en generate_encryptionkey. "sess->Preauth_HashValue" se establece en NULL si la sesión es válida. Por lo tanto, este parche omite la generación de la clave de cifrado si la sesión es válida.
