CVE-2018-3615

CVE-2018-3615 (L1 Terminal Fault: SGX) is a speculative‑execution side‑channel vulnerability affecting Intel SGX: a local attacker can exfiltrate data from an SGX enclave through the L1 data cache. The underlying cause is transient execution that, after a fault is raised, can still leak cache dat...

CVE-2018-3646

CVE-2018-3646 is the L1 Terminal Fault (L1TF) vulnerability affecting systems with Intel CPUs. It allows a local attacker, including guests in virtualized environments, to read data from the L1 data cache via side-channel analysis. Apple’s Hypervisor entry ties this to speculative execution/guest...

Kernel: speculative bounds check bypass store

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an...

Kernel: hw: cpu: L1 terminal fault (L1TF)

Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of...

L1 Terminal Fault speculative side channel

ISSUE DESCRIPTION In x86 nomenclature, a Terminal Fault is a pagetable walk which aborts due to the page being not present e.g. paged out to disk, or because of reserved bits being set. Architecturally, such a memory access will result in a page fault exception, but some processors will...
