Description
In the Linux kernel, the following vulnerability has been resolved: crypto: s390/aes - Fix buffer overread in CTR mode When processing the last block, the s390 ctr code will always read a whole block, even if there isn't a whole block of data left. Fix this by using the actual length left and copy it into a buffer first for processing.
