Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()<br /> <br /> Fix a memory leak in gpi_peripheral_config() where the original memory<br /> pointed to by gchan-&gt;config could be lost if krealloc() fails.<br /> <br /> The issue occurs when:<br /> 1. gchan-&gt;config points to previously allocated memory<br /> 2. krealloc() fails and returns NULL<br /> 3. The function directly assigns NULL to gchan-&gt;config, losing the<br /> reference to the original memory<br /> 4. The original memory becomes unreachable and cannot be freed<br /> <br /> Fix this by using a temporary variable to hold the krealloc() result<br /> and only updating gchan-&gt;config when the allocation succeeds.<br /> <br /> Found via static analysis and code review.
