"Spoiler" is the new flaw researchers discovered affecting all Intel chipsets.

It's slightly different to Spectre and Meltdown as it targets an area of the processor known as Memory Order Buffer.
"The root cause for Spoiler is a weakness in the address speculation of Intel's proprietary implementation of the memory subsystem, which directly leaks timing behavior due to physical address conflicts. Existing Spectre mitigations would therefore not interfere with Spoiler,"
