[7] [2] [12] A stable microcode patch is yet to be delivered, with Intel suggesting that the patch will be ready "in the coming weeks". [ needs update ] [ 7 ] Many operating system vendors will be releasing software updates to assist with mitigating Variant 4; [ 13 ] [ 2 ] [ 14 ] however, microcode/ firmware updates are required for the ...
Intel promised microcode updates to resolve the vulnerability. [1] The microcode patches have been shown to significantly reduce the performance of some heavily-vectorized loads. [7] Patches to mitigate the effects of the vulnerability have also been created as part of the forthcoming version 6.5 release of the Linux kernel. [8]
Meltdown patches may also produce performance loss. [ 11 ] [ 12 ] [ 13 ] It is believed that "hundreds of millions" of systems could be affected by these flaws. [ 3 ] [ 14 ] More security flaws were disclosed on May 3, 2018, [ 15 ] on August 14, 2018, on January 18, 2019, and on March 5, 2020.
In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
A second prominent example is the set of microcode patches that Intel offered for some of their processor architectures of up to 10 years in age, in a bid to counter the security vulnerabilities discovered in their designs – Spectre and Meltdown – which went public at the start of 2018.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
