Last modified Jun 17, 2026

CVE-2015-5276 is a vulnerability of currently unknown severity. The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not properly handle short reads from blocking sources, which makes it easier for context-dependent attackers to predict the random values via unspecified vectors.. EPSS estimates a 2.94% chance of exploitation in the next 30 days.
