  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915/dmc: Add sanity check for DMC load address\n\nFor DMC firmware header version 3, the firmware load address is stored\nin dmc_info->start_mmioaddr and later used by dmc_load_program().\n\nUnlike the MMIO address table, the firmware load address is not\nvalidated. Add a sanity check to ensure it is within the valid range.\n\nBSpec: 69671, 68378\n(cherry picked from commit 5e47ee5c76ca9becde8df4ad5202845b7ffcbc4c)",
