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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
