Memory corruption via concurrent Permissions Document parsing
Published Sep 22, 2026 · Updated Sep 22, 2026
Use-after-free in RTI Connext Professional Security Plugins 7.6.0 allows remote authenticated users to corrupt application memory. Concurrent parsing of multiple Permissions Documents races heap object lifetime, producing out-of-bounds reads and writes. The network path requires valid identity credentials and winning the race; local users who can replace a Permissions Document can also corrupt memory or crash the application.
