Tensorflow is an Open Source Machine Learning Framework. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range. The fix will be included in TensorFlow 2.8.0. The implementation of `GetInitOp` is vulnerable to a crash caused by dereferencing a null pointer. Here, we set `item->kernel` to `nullptr` but it is a simple `OpKernel*` pointer so the memory that was previously allocated to it would leak. If a graph node is invalid, TensorFlow can leak memory in the implementation of `ImmutableExecutorState::Initialize`. We have a similar issue during `IsIdentit圜onsumingSwitch`. If a node is missing, the correposning `mul_*child` would be null, and the dereference in the subsequent line would be incorrect. First, during constant folding, the `GraphDef` might not have the required nodes for the binary operation. There are 2 places where this can occur, for the same malicious alteration of a `SavedModel` file (fixing the first one would trigger the same dereference in the second place). Under certain scenarios, Grappler component of TensorFlow can trigger a null pointer dereference. It should be greater or equal to the current returned data length (`transfer_request -> ux_transfer_request_actual_length`).Ī vulnerability has been identified in Parasolid V33.1 (All versions = V33.1.262 = V35.0.161 = V33.1.262 = V35.0.161 config_proto` is `nullptr`. It must be greater than `UX_HOST_CLASS_PIMA_DATA_HEADER_SIZE`. The following can be used as a workaround: Add check of `header_length`: 1. The fix has been included in USBX release (). An attacker with local access can send a crafted packet to pbx_exchange during registration and cause a NULL pointer exception, effectively crashing the pbx_exchange process.Ī vulnerability has been identified in JTTK (All versions data_length” where if header_length is smaller than UX_HOST_CLASS_PIMA_DATA_HEADER_SIZE, calculation could overflow and then () the calculation of data_length is also overflow, this way the later () can move data_pointer to unexpected address and cause write buffer overflow. The processes with system user UID run on the device would be able to mmap memory pools used by kernel and override them which could be used to gain kernel code execution on the device, gain root privileges, or cause device reboot.Īn issue was discovered in Veritas NetBackup through 8.2 and related Veritas products. The unprivileged process run on the device could disclose sensitive information including kernel pointer, which could be used in further attacks. The impact depends on the privileges of the attacker. OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have a Kernel memory pool override vulnerability in /dev/mmz_userdev device driver. It does not store any personal data.In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices.
