Event History
Frequently Asked Questions
Which systems are most likely to encounter this issue?
The reported trigger is attaching an SST PCI device to a virtual machine. The report was observed on VMware hardware while the kernel CPU hotplug task was running.
What level of access does an attacker need?
The severity vector indicates local access with low privileges is required. No user interaction is required.
What is the likely impact if the issue is triggered?
The reported effect is a KASAN slab-out-of-bounds read in the ISST interface code. The severity vector indicates an availability impact, with no confidentiality or integrity impact listed.
How can I recognize a possible occurrence?
Kernel logs may contain a KASAN "slab-out-of-bounds" report identifying _isst_if_get_pci_dev in the isst_if_common module, potentially during attachment of an SST PCI device to a VM.
