In affected versions under certain conditions…","summary":"TensorFlow's Go bindings can segfault during garbage collection of a string tensor whose encoding failed, for example because of mismatched dimensions. The `C.TF_TString_Dealloc` call in the finalizer assumes encoding succeeded, and tensor structure is only checked at encoding time to avoid a performance penalty. The affected versions are TensorFlow 2.5.1 and earlier versions of the same line.","solution":"Patched in GitHub commit 8721ba96e5760c229217b594f6d2ba332beedf22.
