{"id":"CVE-2026-72406","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-72406","summary":"net: sungem: fix probe error cleanup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: sungem: fix probe error cleanup\n\ngem_init_one() calls gem_remove_one() when register_netdev() fails.\ngem_remove_one() unregisters and frees resources owned by the net_device,\nincluding the DMA block, MMIO mapping, PCI regions, and the net_device\nitself. gem_init_one() then falls through to its own cleanup labels and\nfrees the same resources again.\n\nKeep the register_netdev() error path in gem_init_one(): clear drvdata so\nPM/remove paths do not see a half-registered device, remove the NAPI\ninstance added during probe, and let the existing cleanup labels release\nthe resources once.\n\nThe issue was found by a local static-analysis checker for probe error\npaths. The reported path was manually inspected before sending this fix.\n\nCompile-tested with CONFIG_SUNGEM=y. Runtime testing was not performed\nbecause no sungem hardware is available.","published":"2026-08-15T05:56:30.225Z","modified":"2026-08-18T03:56:43.161281648Z","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":"5.10.261"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/331c99029a1cee1111f82f63d15b3cdebefbd341"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36dea2f639249460d13f6ca66b2a9064187cd34d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a63eaf7605d1579cf3f551792e478cfaf5ac37d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b15a3cc68e2450aa0edd94a74a7bdd45fcc17dd9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc49e8746584564dba47d963d1916cc876fc6f6b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1d04fefb0c2a2de32d9cee22cdc2088be3758d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3bd60b26814b7c3c57c629abb0857dfc76d214a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb73cdc50b6755e5c3a80a195b2708a39ada0230"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72406.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72406"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:43.161281648Z"}}
