Summary
An issue was discovered in MFC in Samsung Mobile Processor and Wearable Processor Exynos 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 2600, 1680, W920, W930, and W1000. A double-free vulnerability in the Exynos MFC encoder driver (due to improper cleanup of dma_buf references during error handling) leads to kernel memory corruption and potential arbitrary code execution.
