Intel Hit by New Spectre Flaw With Data Leak Risk

Researchers at ETH Zurich have uncovered a new method to exploit Intel processors using a variation of the notorious Spectre vulnerability, according to findings published Tuesday. The technique leverages a branch prediction race condition to leak sensitive information from memory, reigniting concerns over speculative execution flaws in modern CPUs.

The exploit, which targets Intel’s processor architecture, enables attackers to manipulate the CPU’s branch prediction mechanism, causing it to access unauthorized memory locations. While the attack method demonstrates a significant security risk, initial patches and mitigations have reportedly resulted in only a mild performance impact.

This latest development underscores the ongoing challenges chipmakers face in fully securing speculative execution features without degrading system performance. Intel has not released an official comment on the findings. The vulnerability adds to a growing list of microarchitectural threats that continue to affect chip security years after Spectre first emerged. Further analysis and industry response are expected in the coming weeks.
