"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915/dmc: Harden DMC firmware payload parsing\n\nValidate the conversion of the DMC firmware size from dwords to bytes\nusing check_mul_overflow() before calculating the firmware payload size.\n\nReject zero-length payloads and zero MMIO counts in the DMC firmware\nheader so malformed firmware is caught early. Also set dmc_fw_size only\nafter the payload allocation succeeds.\n\n(cherry picked from commit efde6601a1f1daedfe3dcc2816c934ddb44e3eef)"
