Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> NFSv4.0: Fix a use-after-free problem in the asynchronous open()<br /> <br /> Yang Erkun reports that when two threads are opening files at the same<br /> time, and are forced to abort before a reply is seen, then the call to<br /> nfs_release_seqid() in nfs4_opendata_free() can result in a<br /> use-after-free of the pointer to the defunct rpc task of the other<br /> thread.<br /> The fix is to ensure that if the RPC call is aborted before the call to<br /> nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid()<br /> in nfs4_open_release() before the rpc_task is freed.
