{"id":"CVE-2026-98579","summary":"nfc: llcp: fix sdreq TLV list leak on parse/alloc/send failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: llcp: fix sdreq TLV list leak on parse/alloc/send failure\n\nnfc_genl_llc_sdreq() builds a list of TLV nodes while walking nested\nnetlink attrs, but 3 error paths (nested-attr parse failure, TLV alloc\nENOMEM, nfc_llcp_send_snl_sdreq() failure) all skip freeing what was\nalready queued.\n\nRoute them through a new free_list label, mirroring the SDRES path in\nthe same file which already does this. Harmless on the success path\ntoo -- send_snl_sdreq() drains the list as it moves nodes, so it's\nalready empty by the time free_list runs.","modified":"2026-10-19T02:46:57.450408317Z","published":"2026-10-18T15:18:52.611Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98579.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/08d2c069239ab425fdd333784a6a3b3e034e4aa0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0b01a946b0f234f5badd25968610b585a4895f08"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b1eca82085134bd92cd3810b0ef003c91e3f668"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66f4300206b82b0b143ef0d9be90cd8d29f23a47"},{"type":"WEB","url":"https://git.kernel.org/stable/c/755bfc409748d8f3df64eb0eb26926270de3dd77"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cbde7f5d326172d6dbb55cca0df42fa7e1ed8115"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3f60a7fc291d08cd9192a3b4cd5d3a223fa7d02"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e43ec0191c1630f41e7043ac729ea6f1b8044a7f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98579.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98579"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d9b8d8e19b073096d3609bbd60f82148d128b555"},{"fixed":"5b1eca82085134bd92cd3810b0ef003c91e3f668"},{"fixed":"d3f60a7fc291d08cd9192a3b4cd5d3a223fa7d02"},{"fixed":"755bfc409748d8f3df64eb0eb26926270de3dd77"},{"fixed":"e43ec0191c1630f41e7043ac729ea6f1b8044a7f"},{"fixed":"08d2c069239ab425fdd333784a6a3b3e034e4aa0"},{"fixed":"cbde7f5d326172d6dbb55cca0df42fa7e1ed8115"},{"fixed":"0b01a946b0f234f5badd25968610b585a4895f08"},{"fixed":"66f4300206b82b0b143ef0d9be90cd8d29f23a47"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98579.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.10.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98579.json"}}],"schema_version":"1.9.0"}
