Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains an issue in the KVM component, specifically within the emulation of Xen schedop poll hypercalls. The kvm xen schedop poll function uses kmalloc array() when a virtual machine (VM) polls the host for multiple event channels. Error paths do not consistently go through the designated "out" label, leading to potential issues during cleanup.
