GHSA-XCGF-679W-PGVP
Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-11-24 21:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix null pointer dereference in tracing_err_log_open()
Fix an issue in function 'tracing_err_log_open'. The function doesn't call 'seq_open' if the file is opened only with write permissions, which results in 'file->private_data' being left as null. If we then use 'lseek' on that opened file, 'seq_lseek' dereferences 'file->private_data' in 'mutex_lock(&m->lock)', resulting in a kernel panic. Writing to this node requires root privileges, therefore this bug has very little security impact.
Tracefs node: /sys/kernel/tracing/error_log
Example Kernel panic:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000038 Call trace: mutex_lock+0x30/0x110 seq_lseek+0x34/0xb8 __arm64_sys_lseek+0x6c/0xb8 invoke_syscall+0x58/0x13c el0_svc_common+0xc4/0x10c do_el0_svc+0x24/0x98 el0_svc+0x24/0x88 el0t_64_sync_handler+0x84/0xe4 el0t_64_sync+0x1b4/0x1b8 Code: d503201f aa0803e0 aa1f03e1 aa0103e9 (c8e97d02) ---[ end trace 561d1b49c12cf8a5 ]--- Kernel panic - not syncing: Oops: Fatal exception

GHSA-XCWJ-WFCM-M23C
Vulnerability from github – Published: 2021-05-21 14:22 – Updated: 2024-10-30 23:19
VLAI
Summary
Invalid validation in `SparseMatrixSparseCholesky`
Details
Impact
An attacker can trigger a null pointer dereference by providing an invalid permutation to tf.raw_ops.SparseMatrixSparseCholesky:
import tensorflow as tf
import numpy as np
from tensorflow.python.ops.linalg.sparse import sparse_csr_matrix_ops
indices_array = np.array([[0, 0]])
value_array = np.array([-10.0], dtype=np.float32)
dense_shape = [1, 1]
st = tf.SparseTensor(indices_array, value_array, dense_shape)
input = sparse_csr_matrix_ops.sparse_tensor_to_csr_sparse_matrix(
st.indices, st.values, st.dense_shape)
permutation = tf.constant([], shape=[1, 0], dtype=tf.int32)
tf.raw_ops.SparseMatrixSparseCholesky(input=input, permutation=permutation, type=tf.float32)
This is because the implementation fails to properly validate the input arguments:
void Compute(OpKernelContext* ctx) final {
...
const Tensor& input_permutation_indices = ctx->input(1);
...
ValidateInputs(ctx, *input_matrix, input_permutation_indices, &batch_size, &num_rows);
...
}
void ValidateInputs(OpKernelContext* ctx,
const CSRSparseMatrix& sparse_matrix,
const Tensor& permutation_indices, int* batch_size,
int64* num_rows) {
OP_REQUIRES(ctx, sparse_matrix.dtype() == DataTypeToEnum<T>::value, ...)
...
}
Although ValidateInputs is called and there are checks in the body of this function, the code proceeds to the next line in ValidateInputs since OP_REQUIRES is a macro that only exits the current function.
#define OP_REQUIRES(CTX, EXP, STATUS) \
do { \
if (!TF_PREDICT_TRUE(EXP)) { \
CheckNotInComputeAsync((CTX), "OP_REQUIRES_ASYNC"); \
(CTX)->CtxFailure(__FILE__, __LINE__, (STATUS)); \
return; \
} \
} while (0)
Thus, the first validation condition that fails in ValidateInputs will cause an early return from that function. However, the caller will continue execution from the next line. The fix is to either explicitly check context->status() or to convert ValidateInputs to return a Status.
Patches
We have patched the issue in GitHub commit e6a7c7cc18c3aaad1ae0872cb0a959f5c923d2bd.
The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

Please consult our security guide for more information regarding the security model and how to contact us with issues and questions.

"details": "### Impact\nAn attacker can trigger a null pointer dereference by providing an invalid `permutation` to `tf.raw_ops.SparseMatrixSparseCholesky`:\n\n```python\nimport tensorflow as tf\nimport numpy as np\nfrom tensorflow.python.ops.linalg.sparse import sparse_csr_matrix_ops\n\nindices_array = np.array([[0, 0]])\nvalue_array = np.array([-10.0], dtype=np.float32)\ndense_shape = [1, 1]\nst = tf.SparseTensor(indices_array, value_array, dense_shape)\n\ninput = sparse_csr_matrix_ops.sparse_tensor_to_csr_sparse_matrix(\n st.indices, st.values, st.dense_shape)\n\npermutation = tf.constant([], shape=[1, 0], dtype=tf.int32)\n \ntf.raw_ops.SparseMatrixSparseCholesky(input=input, permutation=permutation, type=tf.float32)\n```\n\nThis is because the [implementation](https://github.com/tensorflow/tensorflow/blob/080f1d9e257589f78b3ffb75debf584168aa6062/tensorflow/core/kernels/sparse/sparse_cholesky_op.cc#L85-L86) fails to properly validate the input arguments: \n \n```cc \nvoid Compute(OpKernelContext* ctx) final {\n ...\n const Tensor\u0026 input_permutation_indices = ctx-\u003einput(1);\n ...\n ValidateInputs(ctx, *input_matrix, input_permutation_indices, \u0026batch_size, \u0026num_rows);\n ...\n}\n\nvoid ValidateInputs(OpKernelContext* ctx,\n const CSRSparseMatrix\u0026 sparse_matrix,\n const Tensor\u0026 permutation_indices, int* batch_size,\n int64* num_rows) {\n OP_REQUIRES(ctx, sparse_matrix.dtype() == DataTypeToEnum\u003cT\u003e::value, ...)\n ...\n}\n```\nAlthough `ValidateInputs` is called and there are checks in the body of this function, the code proceeds to the next line in `ValidateInputs` since [`OP_REQUIRES`](https://github.com/tensorflow/tensorflow/blob/080f1d9e257589f78b3ffb75debf584168aa6062/tensorflow/core/framework/op_requires.h#L41-L48) is a macro that only exits the current function.\n\n```cc\n#define OP_REQUIRES(CTX, EXP, STATUS) \\\n do { \\\n if (!TF_PREDICT_TRUE(EXP)) { \\\n CheckNotInComputeAsync((CTX), \"OP_REQUIRES_ASYNC\"); \\\n (CTX)-\u003eCtxFailure(__FILE__, __LINE__, (STATUS)); \\\n return; \\\n } \\\n } while (0)\n```\n\nThus, the first validation condition that fails in `ValidateInputs` will cause an early return from that function. However, the caller will continue execution from the next line. The fix is to either explicitly check `context-\u003estatus()` or to convert `ValidateInputs` to return a `Status`.\n\n### Patches\nWe have patched the issue in GitHub commit [e6a7c7cc18c3aaad1ae0872cb0a959f5c923d2bd](https://github.com/tensorflow/tensorflow/commit/e6a7c7cc18c3aaad1ae0872cb0a959f5c923d2bd).\n\nThe fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n### Attribution\nThis vulnerability has been reported by Ying Wang and Yakun Zhang of Baidu X-Team.",

Vulnerability from github – Published: 2025-10-01 12:30 – Updated: 2026-01-20 18:31
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
ionic: catch failure from devlink_alloc
Add a check for NULL on the alloc return. If devlink_alloc() fails and we try to use devlink_priv() on the NULL return, the kernel gets very unhappy and panics. With this fix, the driver load will still fail, but at least it won't panic the kernel.
Severity
5.5 (Medium)

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
No CAPEC attack patterns related to this CWE.
