Overview

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions in the kvm_pkvm_ioctl_allowed process. An attacker can cause a system panic and taint the kernel by passing an unrecognized ioctl number from userspace, which triggers a WARN and, if panic_on_warn is enabled, results in a kernel panic.

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
