x86/Intel: Gather Data Sampling

ISSUE DESCRIPTION A researcher has discovered Gather Data Sampling, a transient execution side-channel whereby the AVX GATHER instructions can forward the content of stale vector registers to dependent instructions. The physical register file is a structure competitively shared between sibling...

USN-6244-1 amd64-microcode vulnerability

Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information...

x86/AMD: Zenbleed

ISSUE DESCRIPTION Researchers at Google have discovered Zenbleed, a hardware bug causing corruption of the vector registers. When a VZEROUPPER instruction is discarded as part of a bad transient execution path, its effect on internal tracking are not unwound correctly. This manifests as the wrong...

SUSE CVE-2019-15030

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction via the hardware transactional memory instruction tbegin and then...

SUSE CVE-2019-15031

In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction via the hardware transactional memory instruction tbegin and then accesses vector registers...

hw: Vector Register Data Sampling

A flaw was found in Intel processors where a local attacker is able to gain information about registers used for vector calculations by observing register states from other processes running on the system. This results in a race condition where store buffers, which were not cleared, could be read...
