Heap overflow in `QuantizeAndDequantizeV2`

ImpactThe function MakeGrapplerFunctionItem takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered.pythonimport tensorflow as [email protected] test:...

PYSEC-2026-3140 Tensorflow vulnerable to Out-of-Bounds Read

Impact When the BaseCandidateSamplerOp function receives a value in trueclasses larger than rangemax, a heap oob vuln occurs. python tf.rawops.ThreadUnsafeUnigramCandidateSampler trueclasses=0x100000,1, numtrue = 2, numsampled = 2, unique = False, rangemax = 2, seed = 2, seed2 = 2 Patches We have...

Invalid char to bool conversion when printing a tensor

ImpactWhen printing a tensor, we get it's data as a const char array since that's the underlying storage and then we typecast it to the element type. However, conversions from char to bool are undefined if the char is not 0 or 1, so sanitizers/fuzzers will crash. PatchesWe have patched the issue ...
