CVE-2018-3640

Systems with microprocessors utilizing speculative execution and that perform speculative reads of system registers may allow unauthorized disclosure of system parameters to an attacker with local user access via a side-channel analysis, aka Rogue System Register Read RSRE, Variant 3a...

CVE-2018-3640

CVE-2018-3640 affects macOS EFI/Hypervisor components on macOS High Sierra 10.13.6 and Mojave 10.14, where systems with speculative execution and speculative reads of system registers may leak information via a side‑channel. The root cause is speculative execution side‑channel disclosures; a micr...

New Spectre (Variant 4) CPU Flaw Discovered—Intel, ARM, AMD Affected

Security researchers from Microsoft and Google have discovered a fourth variant of the data-leaking Meltdown-Spectre security flaws impacting modern CPUs in millions of computers, including those marketed by Apple. Variant 4 comes weeks after German computer magazine Heise reported about a set of...

CVE-2014-5148

Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to...

DEBIAN-CVE-2015-0239

The emsysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service guest OS crash by triggering use of a 16-bit code segment for emulation of a...

Flaw in handling unknown system register access from 64-bit userspace on ARM

ISSUE DESCRIPTION When handling an unknown system register access from 64-bit userspace Xen would incorrectly return to the second instruction of the trap handler for faults in kernel space rather than the first instruction of the trap handler for faults in 64-bit userspace. Any user in a guest...
