Details

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

block: fix potential invalid pointer dereference in blk_add_partition

The blk_add_partition() function initially used a single if-condition (IS_ERR(part)) to check for errors when adding a partition. This was modified to handle the specific case of -ENXIO separately, allowing the function to proceed without logging the error in this case. However, this change unintentionally left a path where md_autodetect_dev() could be called without confirming that part is a valid pointer.

This commit separates the error handling logic by splitting the initial if-condition, improving code readability and handling specific error scenarios explicitly. The function now distinguishes the general error case from -ENXIO without altering the existing behavior of md_autodetect_dev() calls.

Vulnerability from github – Published: 2026-01-21 01:06 – Updated: 2026-01-21 01:06

Summary
ImageMagick has a NULL pointer dereference in MSL parser via <comment> tag before image load
Details

Summary

NULL pointer dereference in MSL (Magick Scripting Language) parser when processing <comment> tag before any image is loaded.

Version

  • ImageMagick 7.x (tested on current main branch)
  • Commit: HEAD

Steps to Reproduce

Method 1: Using ImageMagick directly

magick MSL:poc.msl out.png

Method 2: Using OSS-Fuzz reproduce

python3 infra/helper.py build_fuzzers imagemagick
python3 infra/helper.py reproduce imagemagick msl_fuzzer poc.msl

Or run the fuzzer directly:

./msl_fuzzer poc.msl

Expected Behavior

ImageMagick should handle the malformed MSL gracefully and return an error message.

Actual Behavior

convert: MagickCore/property.c:297: MagickBooleanType DeleteImageProperty(Image *, const char *): Assertion `image != (Image *) NULL' failed.
Aborted

Root Cause Analysis

In coders/msl.c:7091, MSLEndElement() calls DeleteImageProperty() on msl_info->image[n] when handling the </comment> end tag without checking if the image is NULL:

if (LocaleCompare((const char *) tag,"comment") == 0 )
  {
    (void) DeleteImageProperty(msl_info->image[n],"comment");  // No NULL check
    ...
  }

When <comment> appears before any <read> operation, msl_info->image[n] is NULL, causing the assertion failure in DeleteImageProperty() at property.c:297.

Impact

  • DoS: Crash via assertion failure (debug builds) or NULL pointer dereference (release builds)
  • Affected: Any application using ImageMagick to process user-supplied MSL files

Fuzzer

This issue was discovered using a custom MSL fuzzer:

#include <cstdint>
#include <Magick++/Blob.h>
#include <Magick++/Image.h>
#include "utils.cc"

extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size)
{
  if (IsInvalidSize(Size))
    return(0);
  try
  {
    const Magick::Blob blob(Data, Size);
    Magick::Image image;
    image.magick("MSL");
    image.fileName("MSL:");
    image.read(blob);
  }
  catch (Magick::Exception)
  {
  }
  return(0);
}

This issue was found by Team FuzzingBrain @ Texas A&M University

GHSA-5W29-44GV-2G38

Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-01-06 21:30
VLAI
Details

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

mmc: mmc_spi: fix error handling in mmc_spi_probe()

If mmc_add_host() fails, it doesn't need to call mmc_remove_host(), or it will cause null-ptr-deref, because of deleting a not added device in mmc_remove_host().

To fix this, goto label 'fail_glue_init', if mmc_add_host() fails, and change the label 'fail_add_host' to 'fail_gpiod_request'.

Severity
5.5 (Medium)

Vulnerability from github – Published: 2024-09-13 06:30 – Updated: 2026-03-25 12:30
VLAI
Details

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

usb: typec: ucsi: Move unregister out of atomic section

Commit '9329933699b3 ("soc: qcom: pmic_glink: Make client-lock non-sleeping")' moved the pmic_glink client list under a spinlock, as it is accessed by the rpmsg/glink callback, which in turn is invoked from IRQ context.

This means that ucsi_unregister() is now called from atomic context, which isn't feasible as it's expecting a sleepable context. An effort is under way to get GLINK to invoke its callbacks in a sleepable context, but until then lets schedule the unregistration.

A side effect of this is that ucsi_unregister() can now happen after the remote processor, and thereby the communication link with it, is gone. pmic_glink_send() is amended with a check to avoid the resulting NULL pointer dereference. This does however result in the user being informed about this error by the following entry in the kernel log:

ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5

Details

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

spi: sprd: fix error pointer deref after DMA setup failure

The driver falls back to PIO mode if DMA setup fails during probe.

Make sure to check the dma.enabled flag before trying to release the DMA channels also on late probe errors to avoid dereferencing an error pointer (or attempting to release a channel a second time).

This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.

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.
