What is missing is the \ndowngrading of pure zerocopy status to make sure \nsk_forward_alloc will stay synced. \n \nAdd tcp_downgrade_zcopy_pure() helper so that we can \nuse it from the two callers. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"16 Jul 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-07-16T15:26:34.000000Z"} 2024-07-16T15:26:34+00:00
