CVE-2025-40026

CVE-2025-40026 — Linux kernel KVM x86 issue : When completing emulation of an instruction that generated a userspace exit for I/O, the kernel could re-check L1 intercepts even after emulation had completed and the host had effectively allowed L2 to perform the I/O. If the I/O permission bitmaps w...
