If that allocation failed, it set an error message but jumped to the\nsuccess path, returning a policydb with the required table missing.\n\nReturn -ENOMEM through the normal failure path when the ACCEPT2 allocation\nfails. Remove the now-unused out label.","modified":"2026-08-18T03:30:57.213421603Z","published":"2026-08-15T05:57:03.536Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72457.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/106e909e12baf059538f0b0f1a59f87781d25b3c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/22dc9433d458cff1270f120685114a9753e0ad1b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45cf568241048e560a81aa2053f06a62069f5640"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72457.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72457"},{"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":"2e12c5f060176ede209673e4f63ea5d0e3c5814c"},{"fixed":"22dc9433d458cff1270f120685114a9753e0ad1b"},{"fixed":"106e909e12baf059538f0b0f1a59f87781d25b3c"},{"fixed":"45cf568241048e560a81aa2053f06a62069f5640"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72457.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72457.json"}}],"schema_version":"1.9.0"}
