{"id":"CVE-2026-97981","summary":"net: ethernet: cortina: Count dropped frames as NAPI work","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: cortina: Count dropped frames as NAPI work\n\nThe RX loop only consumes budget when it successfully delivers a frame.\nError paths keep consuming descriptors without reducing the budget, so a\nstream of bad frames can process the entire receive ring in one poll.\n\nMove the budget accounting to a common end-of-frame path. This counts\neach completed frame as NAPI work whether it was delivered or dropped,\nmatching the behavior of the vendor driver.","modified":"2026-10-09T17:26:56.243595862Z","published":"2026-09-25T10:23:17.703Z","related":["openSUSE-SU-2026:12074-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97981.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/27b5753077d1cfda5fe201d2ba602de76a9a09b1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5754e0c0758805096ecfeaf4c1b146ad51ed246f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/58140f1cebb776d174dc6ff41c15401654a5b1ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/620b7184808b25cf58268856f892b9ba83c181fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9620e2ce9b5998ebbf157241f296f8ddb92285c2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b856c552f556bc0341c1dbe0bf88e630fd1dc4b7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cceb6cd7f0e5ed2944a9ca22443d7b9da82f60ab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e858b9b1ea3cbbc353189d07dec40dc16967e290"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97981.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97981"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4d5ae32f5e1e13f7f36d6439ec3257993b9f5b88"},{"fixed":"620b7184808b25cf58268856f892b9ba83c181fd"},{"fixed":"9620e2ce9b5998ebbf157241f296f8ddb92285c2"},{"fixed":"27b5753077d1cfda5fe201d2ba602de76a9a09b1"},{"fixed":"e858b9b1ea3cbbc353189d07dec40dc16967e290"},{"fixed":"58140f1cebb776d174dc6ff41c15401654a5b1ea"},{"fixed":"cceb6cd7f0e5ed2944a9ca22443d7b9da82f60ab"},{"fixed":"5754e0c0758805096ecfeaf4c1b146ad51ed246f"},{"fixed":"b856c552f556bc0341c1dbe0bf88e630fd1dc4b7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97981.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.16.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97981.json"}}],"schema_version":"1.9.0"}
