Vulnerability from github – Published: 2022-05-24 22:10 – Updated: 2022-05-24 22:10

Summary

Missing validation results in undefined behavior in `QuantizedConv2D`

Details

Impact

The implementation of tf.raw_ops.QuantizedConv2D does not fully validate the input arguments:

import tensorflow as tf

input = tf.constant(1, shape=[1, 2, 3, 3], dtype=tf.quint8)
filter = tf.constant(1, shape=[1, 2, 3, 3], dtype=tf.quint8)

# bad args
min_input = tf.constant([], shape=[0], dtype=tf.float32)
max_input = tf.constant(0, shape=[], dtype=tf.float32)
min_filter = tf.constant(0, shape=[], dtype=tf.float32)
max_filter = tf.constant(0, shape=[], dtype=tf.float32)

tf.raw_ops.QuantizedConv2D(
  input=input,
  filter=filter,
  min_input=min_input,
  max_input=max_input,
  min_filter=min_filter,
  max_filter=max_filter, 
  strides=[1, 1, 1, 1],
  padding="SAME")

In this case, references get bound to nullptr for each argument that is empty (in the example, all arguments in the bad args section).

Patches

We have patched the issue in GitHub commit 0f0b080ecde4d3dfec158d6f60da34d5e31693c4.

The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.

In the Linux kernel, the following vulnerability has been resolved:

hfs: fix general protection fault in hfs_find_init()

The hfs_find_init() method can trigger the crash if tree pointer is NULL:

Vulnerability from github – Published: 2024-03-04 18:30 – Updated: 2025-01-07 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

ipmi: ssif: initialize ssif_info->client early

During probe ssif_info->client is dereferenced in error path. However, it is set when some of the error checking has already been done. This causes following kernel crash if an error path is taken:

Initialize ssif_info->client before any error path can be taken. Clear i2c_client data in the error path to prevent the dangling pointer from leaking.

Vulnerability from github – Published: 2024-12-29 12:30 – Updated: 2025-01-07 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

net/9p/usbg: fix handling of the failed kzalloc() memory allocation

On the linux-next, next-20241108 vanilla kernel, the coccinelle tool gave the following error report:

./net/9p/trans_usbg.c:912:5-11: ERROR: allocation function on line 911 returns NULL not ERR_PTR on failure

kzalloc() failure is fixed to handle the NULL return case on the memory exhaustion.

Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2024-12-31 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: single: fix potential NULL dereference

Added checking of pointer "function" in pcs_set_mux(). pinmux_generic_get_function() can return NULL and the pointer "function" was dereferenced without checking against NULL.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Revert "drm/gem-shmem: Use dma_buf from GEM object instance"

This reverts commit 1a148af06000e545e714fe3210af3d77ff903c11.

The dma_buf field in struct drm_gem_object is not stable over the object instance's lifetime. The field becomes NULL when user space releases the final GEM handle on the buffer object. This resulted in a NULL-pointer deref.

Workarounds in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") and commit f6bfc9afc751 ("drm/framebuffer: Acquire internal references on GEM handles") only solved the problem partially. They especially don't work for buffer objects without a DRM framebuffer associated.

Hence, this revert to going back to using .import_attach->dmabuf.

Vulnerability from github – Published: 2024-11-19 03:31 – Updated: 2025-11-04 00:32

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: stm32: spdifrx: fix dma channel release in stm32_spdifrx_remove

In case of error when requesting ctrl_chan DMA channel, ctrl_chan is not null. So the release of the dma channel leads to the following issue: [ 4.879000] st,stm32-spdifrx 500d0000.audio-controller: dma_request_slave_channel error -19 [ 4.888975] Unable to handle kernel NULL pointer dereference at virtual address 000000000000003d [...] [ 5.096577] Call trace: [ 5.099099] dma_release_channel+0x24/0x100 [ 5.103235] stm32_spdifrx_remove+0x24/0x60 [snd_soc_stm32_spdifrx] [ 5.109494] stm32_spdifrx_probe+0x320/0x4c4 [snd_soc_stm32_spdifrx]

To avoid this issue, release channel only if the pointer is valid.

Vulnerability from github – Published: 2017-10-24 18:33 – Updated: 2023-07-04 00:01

Summary

ActiveRecord in Ruby on Rails allows database-query bypass

Details

Active Record in Ruby on Rails 4.2.x before 4.2.7.1 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request, as demonstrated by certain "[nil]" values, a related issue to CVE-2012-2660, CVE-2012-2694, and CVE-2013-0155.

Severity

7.5 (High)

GHSA-PR54-G5F8-4JQW

Vulnerability from github – Published: 2024-10-21 15:32 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/cxgb4: Added NULL check for lookup_atid

The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the act_establish() and act_open_rpl() functions. Add a NULL check to prevent null pointer dereferencing.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Severity

5.5 (Medium)
