  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/irdma: Fix OOB read during CQ MR registration  Sashiko pointed out an unrelated bug during a previous patch: https://sashiko.dev/#/patchset/20260512183852.614045-1-jmoroni%40google.com  This change fixes the bug by eliminating the cqmr-\u003esplit field which was not being set properly and instead just checks the CQ resize feature flag directly.  The cqmr-\u003esplit field essentially tracks whether IRDMA_FEATURE_CQ_RESIZE is set, but it was not being set until CQ creation time, which is _after_ CQ memory registration (the only other place where it is referenced).  As a result, it would always be false during MR registration and would therefore cause irdma_handle_q_mem to populate cqmr-\u003eshadow even for GEN_2 HW and beyond:      cqmr-\u003eshadow = (dma_addr_t)arr[req-\u003ecq_pages];  The issue is that for GEN_2 and beyond, req-\u003ecq_pages may be exactly equal to iwmr-\u003epage_cnt and therefore equal to the size of arr, which would cause an OOB read by one.",
