CVE-2024-35801

A vulnerability exists in the Linux kernel (x86/fpu) where the xfd_state variable can become desynchronized from MSR_IA32_XFD during a CPU hotplug event. While the MSR is reset, the per-CPU cached value is not, leading to potential failures in xfd_update_state() . This discrepancy can cause XRSTO...
