Affected users should manually download the security update from the Microsoft Update Catalog website.

Software giant, Microsoft Corp has issued an emergency security update that plugs bugs in Intel Corp’s buggy Spectre firmware patch.

Microsoft’s update comes nearly after a month following Intel’s confirmation that its chips had exploitable vulnerabilities, now known as Meltdown and Spectre, which hackers can use to steal data remotely.

According to Microsoft, system instability triggered by Intel’s faulty patch can, in some cases, cause “data loss or corruption”. Its latest patch prevents computers to reboot unexpectedly.

Microsoft has urged affected customers to manually download its update from the Microsoft Update Catalog website.

The Meltdown vulnerability was specific to chips from Intel, ARM Holdings.

The Spectre vulnerability affected most modern computing devices, including ones which contain chips from Advanced Micro Devices Inc (AMD), Intel and ARM.
