Loading vulnerability…
CVE-2024-26958 is a use-after-free flaw in the Linux kernel NFS subsystem's direct-write handling. While processing asynchronous NFS commit requests, a commit request can complete before subsequent requests have been submitted. The completion path can then invoke direct-write completion more than once for the same nfs_direct_request, causing a reference-count underflow and use-after-free condition. The fix applies the established commit begin/end completion-handling pattern around commit-request processing.
