CVE-2017-10911: Linux Kernel

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka XSA-216.

Affected products

• Linux Linux Kernel: up to and including 4.11.7
