In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix memory leak of PBLE objects On rmmod of irdma, the PBLE object memory is not being freed. PBLE object memory are not statically pre-allocated at function initialization time unlike other HMC objects. PBLEs objects and the Segment Descriptors (SD) for it can be dynamically allocated during scale up and SD's remain allocated till function deinitialization.
