A vulnerability in the Linux kernel's x86 FPU handling was resolved to ensure proper XFD state synchronization on signal delivery. The issue occurs when a non-AMX task is preempted by an AMX-enabled task that modifies the XFD MSR, causing a mismatch in the floating-point state upon resumption. This mismatch can trigger warnings and potentially lead to incorrect CPU state handling. The fix involves updating the XFD state dynamically during signal delivery and task resumption to prevent state inconsistencies.
