  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Replace waitqueue and flag with completion\n\nThe driver previously used a waitqueue along with an explicit\nrequest_done flag, but without proper barriers around request_done.\n\nAn earlier patch by Gui-Dong Han \u003changuidong02@gmail.com\u003e attempted\nto fix this by adding the missing memory barriers. Rather than\nadding the barriers, this patch replaces the waitqueue+flag with\na completion, which is designed for this exact purpose.",
