## Description

In the Linux kernel, the following vulnerability has been resolved:  crypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ  The commit referenced in the Fixes tag removed the 'break' from the else branch in qcom_rng_read(), causing an infinite loop whenever 'max' is not a multiple of WORD_SZ. This can be reproduced e.g. by running:      kcapi-rng -b 67 >/dev/null  There are many ways to fix this without adding back the 'break', but they all seem more awkward than simply adding it back, so do just that.  Tested on a machine with Qualcomm Amberwing processor.
