CVE-2025-58143

🔥 A race condition in the mapping of the reference TSC page lets a guest trick Xen into freeing a page it still needs! ⚡ Think of it like a delivery driver who gets a call saying they shouldn’t come to the house anymore, but the homeowner still has their package on the porch. If the driver acts on that call and takes the package away, the homeowner is left empty-handed! An attacker could exploit this vulnerability to create instability in the guest system, potentially leading to crashes or data loss. This could result in a complete denial of service for the affected guest, making it a staggering threat for anything that relies on stable virtualization. We’re talking about critical systems that could be left hanging!
