As a result, io_uring advances more of the provided buffer ring\nthan was actually filled. Use the actual filled region size to consume\nthe buffer, but still return the full size to preserve MSG_TRUNC\nsemantics.\nTake care with multishot, because that seems to already truncate the\nconsumption based on the available payload size.\nThis was reported in https://github.com/axboe/liburing/issues/1619.\n[axboe: fold in size_t unsigned fix]", "A flaw was found in the Linux kernel's io_uring subsystem. This vulnerability allows a local user to cause a denial of service (DoS) or buffer corruption. When handling network receive operations configured with the packet truncation flag (MSG_TRUNC), the kernel calculates buffer consumption based on the total packet length instead of the bytes actually copied into the buffer. This mismatch causes io_uring to advance the buffer ring past the filled region, resulting in overconsumption of buffers and potential system instability."], "name": "CVE-2026-97618", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Not affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/a:redhat:openshift:4", "fix_state": "Not affected", "package_name": "openshift/ose-rhel-coreos-8", "product_name": "Red Hat OpenShift Container Platform 4"}, {"cpe": "cpe:/a:redhat:openshift:4", "fix_state": "Affected", "package_name": "openshift/ose-rhel-coreos-9", "product_name": "Red Hat OpenShift Container Platform 4"}], "public_date": "2026-09-25T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-97618\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-97618\nhttps://git.kernel.org/pub/scm/linux/security/vulns.git/plain/cve/published/2026/CVE-2026-97618.mbox"], "threat_severity": "Moderate"}
