Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the vmci_host_setup_notify process. An attacker can trigger a general protection fault by causing context->notify_page to be NULL, leading to a kernel crash through crafted ioctl system calls.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
