CVE-2019-18422

An issue was discovered in Xen through 4.12.x allowing ARM guest OS users to cause a denial of service or gain privileges by leveraging the erroneous enabling of interrupts. Interrupts are unconditionally unmasked in exception handlers. When an exception occurs on an ARM system which is handled...

CVE-2019-1125

A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with local access could use this information to reveal private data through a Spectre like side channel. Mitigation For mitigation related information, please refer to the Red Hat Knowledgebase artic...

CVE-2019-18422

CVE-2019-18422 affects the Xen hypervisor (ARM guests) where interrupts are unconditionally unmasked in exception handlers. When an exception occurs on ARM and is handled without changing the processor level, some interrupts can be unmasked during entry, allowing a malicious guest to run critical...

ARM: Interrupts are unconditionally unmasked in exception handlers

ISSUE DESCRIPTION When an exception occurs on an ARM system which is handled without changing processor level, some interrupts are unconditionally enabled during exception entry. So exceptions which occur when interrupts are masked will effectively unmask the interrupts. IMPACT A malicious guest...
