{"id":"CVE-2025-37973","summary":"wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation\n\nCurrently during the multi-link element defragmentation process, the\nmulti-link element length added to the total IEs length when calculating\nthe length of remaining IEs after the multi-link element in\ncfg80211_defrag_mle(). This could lead to out-of-bounds access if the\nmulti-link element or its corresponding fragment elements are the last\nelements in the IEs buffer.\n\nTo address this issue, correctly calculate the remaining IEs length by\ndeducting the multi-link element end offset from total IEs end offset.","modified":"2026-04-16T00:01:08.925017565Z","published":"2025-05-20T16:47:19.074Z","related":["SUSE-SU-2025:02249-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02335-1","SUSE-SU-2025:02538-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20475-1","SUSE-SU-2025:20483-1","SUSE-SU-2025:20493-1","SUSE-SU-2025:20498-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37973.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/023c1f2f0609218103cbcb48e0104b144d4a16dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73dde269a1a43e6b1aa92eba13ad2df58bfdd38e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9423f6da825172b8dc60d4688ed3d147291c3be9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1c6d0c6199bd5f4cfc7a66ae7032b6e805f904d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37973.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37973"},{"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":"2481b5da9c6b2ee1fde55a1c29eb2ca377145a10"},{"fixed":"73dde269a1a43e6b1aa92eba13ad2df58bfdd38e"},{"fixed":"9423f6da825172b8dc60d4688ed3d147291c3be9"},{"fixed":"e1c6d0c6199bd5f4cfc7a66ae7032b6e805f904d"},{"fixed":"023c1f2f0609218103cbcb48e0104b144d4a16dc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-37973.json"}}],"schema_version":"1.7.5"}
