In the Linux kernel, the following vulnerability has been resolved: KVM: guestmemfd: Remove bindings on memslot deletion when gmem is dying When unbinding a memslot from a guestmemfd instance, remove the bindings even if the guestmemfd file is dying, i.e. even if its file refcount has gone to zer...

CVE-2025-40274

CVE-2025-40274 (Linux kernel KVM guest_memfd) : The issue arises when unbinding a memslot from a guest_memfd instance if the guest_memfd is dying (file refcount zero). Bindings are not protected against this lifecycle, so a memslot freed before the file is fully released can cause a write to free...
