Overview
Affected versions of this package are vulnerable to Information Exposure via the pvcalls_front_event_handler process. An attacker can corrupt kernel heap memory and potentially disclose or modify arbitrary guest-kernel memory by sending crafted responses with out-of-range req_id values from a malicious or compromised backend.
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
