      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (ltc4282) Clamp negative current limits\n\nWhen a negative value is passed to ltc4282_write_curr(), the signed long\nval is cast directly to u64:\n\ndrivers/hwmon/ltc4282.c:ltc4282_write_curr() {\n        /* need to pass it in millivolt */\n        u32 in = DIV_ROUND_CLOSEST_ULL((u64)val * st->rsense, DECA * MICRO);\n        ...\n}\n\nThis cast converts negative inputs into large positive values. The\nsubsequent division result overflows the u32 in variable, truncating\nto a pseudo-random positive value. When this is passed to\nltc4282_write_voltage_byte(), it is clamped to the maximum limit instead\nof zero.\n\nClamp val to 0 and to the maximum supported upper limit before the cast\nand assign the result to a 64-bit temporary variable before the division\nto avoid the underflow and an also possible overflow.",
