CVE-2025-37964

CVE-2025-37964 relates to the Linux kernel x86/mm TLB handling. The issue is a bug in should_flush_tlb() that can suppress TLB flushes in a narrow window between load_new_mm_cr3() and writing the new mm state into loaded_mm, risking missed TLB flushes during address space switch. The fix widens t...
