Researchers Blame ‘Monolithic’ Linux Code Base for Critical Vulnerabilities

In an exhaustive study of critical Linux vulnerabilities, a team of academic and government-backed researchers claim to have proven that almost all flaws could be mitigated to less than critical severity – and that 40 percent could be completely eliminated – with an OS design based on a verified...

ALPINE-CVE-2018-15468

An issue was discovered in Xen through 4.11.x. The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably not to lock up the...

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...

Intel processors’ vulnerability, related to the possibility of speculative execution commands, allows attackers to circumvent the memory isolation mechanism of virtual machines.

Intel processors’ vulnerabilities are related to the possibility of speculative execution of instructions. Exploiting these vulnerabilities can allow attackers to gain access to the memory of the supervisor or other virtual machines by overcoming the mechanism that isolates virtual machine memory...

Chrome Now Features Site Isolation to Defend Against Spectre

Google introduced new security mitigations for its Chrome browser to defend against recently discovered Spectre variants. The new security feature, called site isolation, essentially isolates different browser work processes between various browser tabs. That means one tab’s webpage rendering and...
