{"id":"CVE-2026-97982","summary":"net: ethernet: cortina: Fix budget accounting","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: cortina: Fix budget accounting\n\nThe gmac_rx() function returns the remaining NAPI budget, but its\ncaller treats the return value as the number of packets received. An\nidle poll therefore reports a full budget and remains scheduled.\n\nReturn the number of received packets instead. Preserve the existing\nfree queue refill accounting by adding that count directly; continuing\nto subtract it from the budget would invert the refill behavior.","modified":"2026-09-26T03:48:42.499286066Z","published":"2026-09-25T10:23:18.304Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97982.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0ef8eaef5806c84db2334111d6f299c246a592bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/631c47e2e1154f2741c555b91df1b8cb99294c6a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94e06e12a376710587cfeea481b65e7c49747003"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a0de06d0da78a3db53de65dfd7452cc6d111f703"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97982.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97982"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4d5ae32f5e1e13f7f36d6439ec3257993b9f5b88"},{"fixed":"631c47e2e1154f2741c555b91df1b8cb99294c6a"},{"fixed":"0ef8eaef5806c84db2334111d6f299c246a592bc"},{"fixed":"94e06e12a376710587cfeea481b65e7c49747003"},{"fixed":"a0de06d0da78a3db53de65dfd7452cc6d111f703"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97982.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.16.0"},{"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/cve-osv-conversion/osv-output/CVE-2026-97982.json"}}],"schema_version":"1.9.0"}
