  "details": "In the Linux kernel, the following vulnerability has been resolved:  mctp i2c: initialise event handler read bytes  Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads will return \"val\" from the i2c bus driver. For i2c-aspeed and i2c-npcm7xx that is a stack uninitialised u8.  Tested with \"i2ctransfer -y 1 r10@0x34\" where 0x34 is a mctp-i2c instance, now it returns all 0xff.",
