Are You in the 2.5% Who Meet This Cybersecurity Job Requirement?

Of course you’re special. So are we. But decades of research tells us humans believe they’re good multitaskers – and we are really, seriously not. It seems a measly 2.5% of us can multitask well. The rest of us are best when we focus on a single goal, allowing the left and right sides of our brai...

GHSA-G9FW-9X87-RMRJ Privilege Context Switching Error in Elasticsearch

The vulnerability of the Lazy FPU context switching function in Intel processors allows a hacker to gain access to protected information.

The vulnerability of the Lazy FPU context switching function in Intel processors is related to insufficient protection of data in the FPU registers of the processor. Exploiting this vulnerability can allow an attacker to access protected information...

Fedora 28 : xen (2018-d3cb6f113c)

Speculative register leakage from lazy FPU context switching XSA-267, CVE-2018-3665 fix for change in iasl output Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and forma...

Speculative register leakage from lazy FPU context switching

ISSUE DESCRIPTION x86 has a hardware mechanism for lazy FPU context switching. On a task switch, %cr0.ts Task Switched gets set, and the next instruction to touch floating point state raises an NM No Math, later known as Device Not Available exception. Traditionally, FPU state has been large in...

CVE-2016-3157

The switchto function in arch/x86/kernel/process64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service guest OS crash, or obtain sensitive information by leveraging I/O port access...

I/O port access privilege escalation in x86-64 Linux

ISSUE DESCRIPTION IRET and POPF do not modify EFLAGS.IOPL when executed by code at a privilege level other than zero. Since PV Xen guests run at privilege level 3 for 64-bit ones; 32-bit ones run at privilege level 1, to compensate for this the context switching of EFLAGS.IOPL requires the guest ...
