Overview

Affected versions of this package are vulnerable to Use After Free in the kvm_ioapic_eoi_inject_work process. An attacker can achieve arbitrary code execution, kernel memory disclosure, and denial of service by triggering a race condition where delayed I/O APIC EOI handling is processed after virtual CPUs are destroyed, leading to use of freed memory during IRQ delivery from pending work.

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
