Heap out-of-bounds read and write via misindexing
Published Feb 4, 2022 · Updated Apr 22, 2025
Heap out-of-bounds access in TensorFlow before 2.5.3, 2.6.0 through 2.6.2, and 2.7.0 allows remote authenticated users to read or write memory. SpecializeType iterates mutable type arguments using the inner-loop index but passes the outer-loop index to mutable_args, selecting beyond the argument vector. Exploitation requires attacker-controlled type metadata to reach graph type specialization; success exposes or corrupts process memory and can crash the process.

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=< 2.5.3
- Affected versionversion=>= 2.6.0, < 2.6.3
- Affected versionversion=>= 2.7.0, < 2.7.1
