  "details": "In the Linux kernel, the following vulnerability has been resolved:  hwmon: (pmbus/core) honor vrm_version in pmbus_data2reg_vid()  pmbus_data2reg_vid() hardcoded the VR11 encoding regardless of the vrm_version configured by the driver, while pmbus_reg2data_vid() already switched on it. Any driver that selects a non-VR11 VID mode and exposes a regulator (or hwmon vout setter) sent dangerously wrong codes to PMBUS_VOUT_COMMAND -- e.g. an nvidia195mv part asked for 200 mV got the VR11 clamp to 500 mV encoded as 0xB2, which the chip interprets as 1080 mV.  Mirror pmbus_reg2data_vid() so writes round-trip with reads.",
