      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Fix OOB read during CQ MR registration\n\nSashiko pointed out an unrelated bug during a previous patch:\nhttps://sashiko.dev/#/patchset/20260512183852.614045-1-jmoroni%40google.com\n\nThis change fixes the bug by eliminating the cqmr->split field which\nwas not being set properly and instead just checks the CQ resize\nfeature flag directly.\n\nThe cqmr->split field essentially tracks whether IRDMA_FEATURE_CQ_RESIZE\nis set, but it was not being set until CQ creation time, which is _after_\nCQ memory registration (the only other place where it is referenced).\n\nAs a result, it would always be false during MR registration and would\ntherefore cause irdma_handle_q_mem to populate cqmr->shadow even for GEN_2\nHW and beyond:\n\n    cqmr->shadow = (dma_addr_t)arr[req->cq_pages];\n\nThe issue is that for GEN_2 and beyond, req->cq_pages may be exactly equal\nto iwmr->page_cnt and therefore equal to the size of arr, which would cause\nan OOB read by one.",
