CVE-2017-11671 describes a vulnerability in GNU Compiler Collection (GCC) versions 4.6 through 6.3, where the ix86_expand_builtin function can generate incorrect instruction sequences for RDRAND and RDSEED intrinsics. This flaw can prevent the status flag from being read, potentially leading to unreported failures of these instructions and reduced randomness in number generation. Rated Medium severity (CVSS 4.0), it requires local access (AV:L) and has a low impact on confidentiality (C:L) with no integrity or availability impact. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed on the CISA KEV catalog.
