Intel CPUs Face Spectre-Like 'Indirector' Attack That Leaks Data
"Indirector" targets a speculative execution component in silicon that previous research has largely overlooked.
Intel Corporation designs processors and platforms whose firmware, microcode, and hardware flaws can affect system security, isolation, and data protection.

Background for this topic.
Intel Corporation is a semiconductor designer whose processors, chipsets, firmware, and platform components underpin many servers, PCs, and embedded systems. In security news, the tag usually concerns vulnerabilities or mitigations affecting this hardware and its supporting software, rather than “intel” meaning threat intelligence.
Security impact can arise below the operating-system boundary: speculative-execution flaws may expose data through side channels, while firmware or platform-management weaknesses can enable privilege escalation or persistence in some configurations. Intel security advisories, operating-system updates, BIOS or UEFI releases, and microcode updates (small processor-control patches) therefore form a coordinated remediation chain. Administrators should inventory affected processor generations and firmware versions, apply trusted updates where applicable, and assess performance or compatibility trade-offs. Researchers and defenders may also need to distinguish hardware limitations from software bugs when investigating suspected exploitation.
"Indirector" targets a speculative execution component in silicon that previous research has largely overlooked.
Modern CPUs from Intel, including Raptor Lake and Alder Lake, have been found vulnerable to a new side-channel attack that could be exploited to leak sensitive information from the processors
Modern Intel processors, including chips from the Raptor Lake and the Alder Lake generations are susceptible to a new type of a high-precision Branch Target Injection (BTI) attack dubbed 'Indirector,' which could be used to steal sensitive information from the CPU. [...]
