Microsoft has disabled an Intel security patch because it was causing unexpected reboots on Windows computers.
(CCM) — Microsoft has been forced to disable an Intel security patch which was designed to fix a bug in the chip-maker's microprocessors because it was causing computers to crash and reboot unexpectedly, according to a BBC report.
The security patch was supposed to remove the Intel security vulnerability from computers running Microsoft's Windows 7, 8.1, and 10 operating systems, but a Microsoft software update for these operating systems disables Intel's flawed patch and stops the rebooting issue according to the report.
Microsoft warned that running the Intel patch could lead to data loss or corruption in some circumstances, adding that it had disabled it as a temporary measure "while Intel tests, updates and deploys new microcode."
Disabling the patch also makes the computers vulnerable again to the Spectre and Meltdown security flaws that the patch was designed to fix. By exploiting Spectre or Meltdown, hackers may be able to steal data that is meant to be secure, although so far there have been no reports of this having actually been achieved, according to Microsoft.
Intel says that it has reproduced the rebooting problem in its labs, and it is making progress towards identifying the root cause. Once it has done this the company should be in a position to issue a new security patch which fixes the Meltdown and Spectre flaws again.
