CVE-2019-15847 (GCVE-0-2019-15847)

Vulnerability from cvelistv5 – Published: 2019-09-02 22:03 – Updated: 2024-08-05 01:03
VLAI?
Summary
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.
Severity ?
