Meltdown is one of the two original transient execution CPU vulnerabilities (the other being Spectre). Meltdown affects Intel x86 microprocessors, IBM POWER processors, and some ARM-based microprocessors. It allows a rogue process to read all memory, even when it is not authorized to do so. Meltdown affects a wide … See more 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 See more On 8 May 1995, a paper called "The Intel 80x86 Processor Architecture: Pitfalls for Secure Systems" published at the 1995 IEEE Symposium on Security and Privacy warned against a covert timing channel in the CPU cache and translation lookaside buffer (TLB). … See more Mitigation of the vulnerability requires changes to operating system kernel code, including increased isolation of kernel memory from user-mode processes.
