AI-suggested
A fix is available and has been applied in the Linux kernel. Users should update to the fixed kernel versions containing the relevant commits to resolve the memory leak. No additional mitigation actions are required.
Description
A memory leak vulnerability was identified and fixed in the Linux kernel's dmaengine Qualcomm GPI driver. The flaw occurs in the gpi_peripheral_config() function when krealloc() fails, causing the original memory reference to be lost and leaked. The fix ensures that gchan->config is only updated if the memory reallocation succeeds, preventing the leak.
