A flaw was found in the way ansi cprng implementation in the Linux kernel processed non-block size aligned requests. If several small requests are made that are less than the instances block size, the remainder for loop code doesn't increment rand_data_valid in the last iteration, meaning that the last bytes in the rand_data buffer gets reused on the subsequent smaller-than-a-block request for random data. Acknowledgements: Red Hat would like to thank Stephan Mueller for reporting this issue.
