CVE-2025-38351

CVE-2025-38351 affects the Linux kernel KVM component (x86) when Hyper-V hypercalls are enabled. The issue arises in PV TLB flush processing where non-canonical GVAs can reach INVVPID/INVLPGA paths, potentially triggering VM-Fail on Intel hardware (AMD may ignore). In practice, this can allow a g...

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...
