PYSEC-2026-973 TensorFlow has Null Pointer Error in LookupTableImportV2

Impact The function tf.rawops.LookupTableImportV2 cannot handle scalars in the values parameter and gives an NPE. python import tensorflow as tf v = tf.Variable1 @tf.functionjitcompile=True def test: func = tf.rawops.LookupTableImportV2 para='tablehandle': v.handle,'keys': 62.98910140991211,...

PYSEC-2026-1005 TensorFlow vulnerable to `CHECK` failures in `UnbatchGradOp`

Impact The UnbatchGradOp function takes an argument id that is assumed to be a scalar. A nonscalar id can trigger a CHECK failure and crash the program. python import numpy as np import tensorflow as tf id is not scalar tf.rawops.UnbatchGradoriginalinput= tf.constant1,batchindex=tf.constant0,0,0 ...

PYSEC-2026-1031 TensorFlow vulnerable to `CHECK` fail in `FakeQuantWithMinMaxVarsGradient`

Impact When tf.quantization.fakequantwithminmaxvarsgradient receives input min or max that is nonscalar, it gives a CHECK fail that can trigger a denial of service attack. python import tensorflow as tf import numpy as np arg0=tf.constantvalue=np.random.randomsize=2, 2, shape=2, 2, dtype=tf.float...

GHSA-WW9Q-8R59-XV46 Zebra: Missing copy constraint in halo2_gadgets variable-base scalar multiplication allows under-constrained base, breaking Orchard Action circuit soundness

Summary A soundness vulnerability in the variable-base scalar multiplication gadget of halo2gadgets allowed a malicious prover to produce a valid proof for an Orchard Action with an under-constrained base point. Because this gadget enforces the diversified-address-integrity condition of the Orcha...

PYSEC-2026-1024 TensorFlow vulnerable to `CHECK` fail in `tf.sparse.cross`

Impact If tf.sparse.cross receives an input separator that is not a scalar, it gives a CHECK fail that can be used to trigger a denial of service attack. python import tensorflow as tf tf.sparse.crossinputs=,name='a',separator=tf.constant'a', 'b',dtype=tf.string Patches We have patched the issue ...

PYSEC-2026-1002 Missing validation crashes `QuantizeAndDequantizeV4Grad`

Impact The implementation of tf.rawops.QuantizeAndDequantizeV4Grad does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack: python import tensorflow as tf tf.rawops.QuantizeAndDequantizeV4Grad gradients=tf.constant1,...

CVE-2026-10512

The X25519 x8664 assembly implementation fails to clear the most significant bit during the final modular reduction, so the computed result may not be fully reduced modulo the field prime 2^255 - 19. This can leave the field element in a non-canonical form, producing an incorrect result from the...

CVE-2026-53081

In the Linux kernel, the following vulnerability has been resolved: bpf: Enforce regsafe base id consistency for BPFADDCONST scalars When regsafe compares two scalar registers that both carry BPFADDCONST, checkscalarids maps their full compound id aka base | BPFADDCONST flag as one idmap entry...

These are only allowed in subprograms when...

CVE-2026-53081

The CVE-2026-53081 issue affects the Linux kernel BPF verifier: when two scalar registers carry BPF_ADD_CONST, id mapping could become inconsistent because the compound id (base | ADD_CONST) was mapped without validating the underlying base IDs. This could allow two verifier states where one deri...

CVE-2026-53032

CVE-2026-53032 affects the Linux kernel BPF subsystem, specifically map_kptr_match_type used with scalar registers. The root cause was a NULL dereference when checking reg->btf in a path taken before verifying base_type(), leading to dereferencing a NULL btf pointer for kptr slots. The fix mov...
