Intel shares fall due processor bugs and lawsuits on class action

Intel Corp. (INTC.O) shares fell as investors worried about the cost of fixing chip bugs. Shares fell nearly 3 percent on Thursday as investors worried about a bug in the newly disclosed computer microprocessors that many companies use would make the cost expensive for mitigation.

The microprocessor giant on Wednesday confirmed the vulnerability expressed by a group of researchers where impacts on computers, phones and other devices. Apple Inc., Microsoft Corp. and other software makers soon released patches to reduce the impact that hackers can exploit to steal sensitive data.

Lawyers filed lawsuits to federal court on Wednesday in San Jose, to raise class action by Intel chip buyers. Open lawsuits have been filed, but Intel's largest customers tend to secretly seek compensation for losses, including the cost of replacing microprocessors.

These customers include computer makers, Internet companies and cloud computing using Intel processors. It is difficult to estimate the amount of compensation. Intel shares fell 2.8 percent at midday following a 3.4 percent drop on Wednesday.
