CVE-2019-15847: 1 source package rows (gcc); 1 state rows across 1 repos (3.11-main); fixed 1, open 0.
The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same.
