CVE-2025-21839

CVE-2025-21839 concerns the Linux kernel KVM DR6 handling. The core issue is that DR6 value loading was handled differently from DR0–DR3, with the guest DR6 value being loaded inside the core vcpu_run loop for KVM_DEBUGREG_BP_ENABLED, and saved on VM-Exit outside the loop. This could allow a gues...
