Otherwise,\nwhen the size grows, the virtnet_rx_resume() causes a write\npast the end of the array. This is easily reproducable with\n\n    ethtool -G ens3 rx 32\n    ./xdpsock -i eth0 -q 0 -r -z &\n    ethtool -G eth0 rx 256","published":"2026-09-17T16:06:39.122Z","modified":"2026-09-19T03:47:28.662225594Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.2.6"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8344c9233c8f77017174d9e280c5a26034d068b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d09c98a6da215bce2173a292e4b95c8de6ea5d51"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90142.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90142"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:47:28.662225594Z"}}
