1. EXECUTIVE SUMMARY CVSS v3 5.5 ATTENTION: Low attack complexity Vendor: Siemens Equipment: Siemens Industrial Products containing certain processors Vulnerability: Exposure of Sensitive Information to an Unauthorized Actor 2. UPDATE INFORMATION This updated advisory is a follow-up to the...

Intel, ARM, IBM, AMD Processors Vulnerable to New Side-Channel Attacks

It turns out that the root cause behind several previously disclosed speculative execution attacks against modern processors, such as Meltdown and Foreshadow, was misattributed to 'prefetching effect,' resulting in hardware vendors releasing incomplete mitigations and countermeasures. Sharing its...

MGASA-2020-0298 Updated microcode packages fix security vulnerability

Incomplete cleanup from specific special register read operations in some IntelR Processors may allow an authenticated user to potentially enable information disclosure via local access. CVE-2020-0543 Cleanup errors in some IntelR Processors may allow an authenticated user to potentially enable...

Medium: microcode_ctl

Issue Overview: A new domain bypass transient execution attack known as Special Register Buffer Data Sampling SRBDS has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker...

UBUNTU-CVE-2019-19338

A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort TAA error occurs. When a guest is running on a host CPU affected by the TAA flaw TAANO=0, but is no...

DEBIAN-CVE-2020-15567

An issue was discovered in Xen through 4.13.x, allowing Intel guest OS users to gain privileges or cause a denial of service because of non-atomic modification of a live EPT PTE. When mapping guest EPT nested paging tables, Xen would in some circumstances use a series of non-atomic bitfield write...

hw: L1D Cache Eviction Sampling

A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents which were expected to be blank can be inferred usi...
