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