CVE-2024-35791 is a use-after-free vulnerability in the Linux kernel KVM Secure Virtual Machine (SVM) encrypted-region registration path, specifically svm_register_enc_region(). The function flushed converted pages after releasing kvm->lock, allowing another task to free the encrypted-region object or its dynamically allocated page array while the flush operation still referenced them. The fix performs the page cache flush while holding kvm->lock.
