CVE-2025-39966

CVE-2025-39966 (Linux kernel, iommufd) : A race during abort for file descriptors could cause a use-after-free when the object is freed while a file’s private_data references it. The bug arises because fput() defers release() to a workqueue; ifAbort allocation fails before installing the file, th...
