On intermediate failures it returned -ENOMEM\ndirectly, leaking resources allocated earlier in the function.\n\nRework the failure path to use staged local unwind labels and free\nallocated resources in reverse order before returning -ENOMEM. This\nmatches common netdev allocation cleanup style.","modified":"2026-05-18T05:59:54.515279623Z","published":"2026-05-01T14:14:34.229Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31737.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/184b3a500d60ea48d1b176103cff1706c456edf3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78da43320d9d6ed788147fb085184e4fc801f057"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82f86111f0704ab2ded11a2033bc6cf0be3e09ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8351d18989c8642fc53e2e12d94e42314a39b078"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a71911fc7eeea930153322bc1efc065db8cd97e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a7e1bf392acf11dc4209820fef75758f6e42bd65"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0fd0fe745f5e8c568d898cd1513d0083e46204a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d45230081f19c280096241353c26b0de457de795"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31737.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31737"},{"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":"d72e01a0430f8a1ae7adb3cbf0b2e73fcd99252e"},{"fixed":"184b3a500d60ea48d1b176103cff1706c456edf3"},{"fixed":"78da43320d9d6ed788147fb085184e4fc801f057"},{"fixed":"a7e1bf392acf11dc4209820fef75758f6e42bd65"},{"fixed":"8a71911fc7eeea930153322bc1efc065db8cd97e"},{"fixed":"d45230081f19c280096241353c26b0de457de795"},{"fixed":"8351d18989c8642fc53e2e12d94e42314a39b078"},{"fixed":"82f86111f0704ab2ded11a2033bc6cf0be3e09ea"},{"fixed":"c0fd0fe745f5e8c568d898cd1513d0083e46204a"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31737.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.168"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.134"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.81"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-31737.json"}}],"schema_version":"1.7.5"}
