CVE-2026-43315 KVM: nSVM: Remove a user-triggerable WARN on nested_svm_load_cr3() succeeding

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Remove a user-triggerable WARN on nestedsvmloadcr3 succeeding Drop the WARN in svmsetnestedstate on nestedsvmloadcr3 failing as it is trivially easy to trigger from userspace by modifying CPUID after loading CR3. E.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...

CVE-2025-37964 x86/mm: Eliminate window where TLB flushes may be inadvertently skipped

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Eliminate window where TLB flushes may be inadvertently skipped tl;dr: There is a window in the mm switching code where the new CR3 is set and the CPU should be getting TLB flushes for the new mm. But shouldflushtlb has a...

CVE-2024-50115

CVE-2024-50115 is a Linux kernel vulnerability affecting KVM nSVM where loading PDPTEs from memory incorrectly handles nCR3[4:0]. The issue can cause an out-of-bounds read if a target page is at the end of a memslot, due to not enforcing 32-byte alignment when PAE paging is used. The root cause i...
