CVE-2025-39823

CVE-2025-39823 is a Linux kernel KVM/CPU virtualization vulnerability affecting x86 where indices from the guest (min, dest_id) were used with array_index_nospec after bounds checks. The issue enables speculative execution side-channel leakage affecting confidentiality, integrity, and availabilit...

CVE-2025-39823 KVM: x86: use array_index_nospec with indices that come from guest

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: use arrayindexnospec with indices that come from guest min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks clamps these values to mitigate speculative execution side-channels...
