  Intel's Mitigation For CVE-2019-14615 Graphics Vulnerability Obliterates Gen7 iGPU Performance

  " It didn't sound too bad at first but then seeing Ivy Bridge Gen7 and Haswell Gen7.5 graphics are also affected raised eyebrows especially with that requiring a much larger mitigation. Now in testing the performance impact, the current mitigation patches completely wreck the performance of Ivybridge/Haswell graphics performance.
  
  The vulnerability being discussed and analyzed this week is CVE-2019-14615. This CVE still hasn't been made public over 24 hours later (though there are the Intel SA-00314 details for this disclosure), but from going through kernel patches and other resources, it certainly caught our interest right away and have been benchmarking it since yesterday evening. The CVE-2019-14615 vulnerability amounts to a new information disclosure issue due to insufficient control flow in certain data structures. Local access is required for exploiting this control flow issue in the hardware, but it's not yet known/published if say WebGL within web browsers could exploit this issue. This is a hardware issue with all operating systems being affected. Our testing today, of course, is under Linux."

  A Java2D például extrém módon visszaesett ..
  remélem lesz jobb javítás is.
