CVE-2024-35801

A vulnerability exists in the Linux kernel (x86/fpu) where the per-CPU variable xfd_state is not reset during CPU hotplugging . While the MSR_IA32_XFD value is reset to the initial state, the cached xfd_state remains stale, causing them to fall out of sync. This discrepancy can cause a subsequent...
