CVE-2023-54055

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/irdma: Fix memory leak of PBLE objects<br /> <br /> On rmmod of irdma, the PBLE object memory is not being freed. PBLE object<br /> memory are not statically pre-allocated at function initialization time<br /> unlike other HMC objects. PBLEs objects and the Segment Descriptors (SD)<br /> for it can be dynamically allocated during scale up and SD&amp;#39;s remain<br /> allocated till function deinitialization.<br /> <br /> Fix this leak by adding IRDMA_HMC_IW_PBLE to the iw_hmc_obj_types[] table<br /> and skip pbles in irdma_create_hmc_obj but not in irdma_del_hmc_objects().
