Data corruption and crash via rollover race
Published May 8, 2025 · Updated Dec 16, 2025
Out-of-bounds memory access in RTI Connext Professional Recording Service allows authenticated attackers to corrupt data or crash it. A race during size-based file rollover causes Recording Service to read or write outside a memory buffer while processing published data or a malicious database. Affected versions span 6.0.0 through 6.0.1.41, 6.1.0 through 6.1.2.22, 7.0.0 through 7.3.0.6, and 7.4.0 through 7.4.x; exploitation requires size-based rollover and winning the race, while network publication applies only without topic security.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=6.0.0 <6.0.1.42
- Affected versionversion=6.1.0 <6.1.2.23
- Affected versionversion=7.0.0 <7.3.0.7
- Affected versionversion=7.4.0 <7.5.0
