AI-suggested
A patch is available and should be applied to affected Linux kernel versions to ensure the frwr_wp_create() failure is properly handled during connection setup. This prevents the NULL pointer dereference and maintains correct connection state. No additional mitigation is required beyond applying the official fix.
Description
A vulnerability in the Linux kernel's xprtrdma subsystem was resolved involving improper handling of the frwr_wp_create() function during connection setup. The function creates a singleton Memory Region for padding write chunks, but failure paths leave a pointer NULL, which was not checked, leading to a potential NULL pointer dereference during certain NFS/RDMA read operations. This flaw is locally triggerable on an NFS/RDMA client due to local memory region allocation failures and cannot be forced remotely. The fix ensures the connection fails properly on such errors, preventing the dereference.
