Intel Processors Denial-of-Service Vulnerability via Improper Finite State Machine Logic

A denial-of-service vulnerability has been identified in some Intel processors, including the 12th, 13th, and 14th Generation Intel Core processors, Intel Core Ultra processors, and 4th and 5th Generation Intel Xeon Scalable processors. This vulnerability arises from improper finite state machines in hardware logic, which may allow a privileged user to disrupt service via local access.

Impact

Exploitation of this vulnerability can lead to a denial-of-service condition, causing affected systems to become unresponsive or unavailable.

Remediation

Intel has released microcode updates for the affected processors, available on the public Intel GitHub repository. Users are advised to update to the latest version provided by their system manufacturer that addresses this issue.
