In the Linux kernel, the following vulnerability has been resolved: NFSv4.1: zero referring call lists before decoding decodecbsequenceargs() allocates csarclists with kmallocobjs(), so each referringcalllist starts uninitialized. decoderclist() assigns rclrefcalls only when rclnrefcalls is nonzero. A valid list with zero referring calls therefore leaves the pointer uninitialized, and nfs4callbacksequence() later passes stale slab contents to kfree(). Allocate csarclists with kzallocobjs() so every rclrefcalls member is NULL from the beginning, including valid empty referring call lists.
