"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwmon: (pmbus/adm1266) widen blackbox-info buffer to I2C_SMBUS_BLOCK_MAX\n\nadm1266_nvmem_read_blackbox() declares a 5-byte stack buffer and\npasses it to i2c_smbus_read_block_data() to retrieve the 4-byte\nBLACKBOX_INFO response. i2c_smbus_read_block_data() does not honour\ncaller buffer sizes -- it memcpy()s data.block[0] bytes from the\nSMBus transaction (where data.block[0] is the length byte returned by\nthe slave device, up to I2C_SMBUS_BLOCK_MAX = 32):\n\n\tmemcpy(values, &data.block[1], data.block[0]);\n\nIf the device returns any block length above 5, the call overflows\nthe caller's 5-byte stack buffer before the post-call\n\n\tif (ret != 4)\n\t\treturn -EIO;\n\ncheck has a chance to reject the response.\n\nWiden the local buffer to I2C_SMBUS_BLOCK_MAX so the helper has room\nfor any well-formed SMBus block response, matching the convention used\nby the other i2c_smbus_read_block_data() callers in this driver."
