{"id":"CVE-2026-46102","summary":"net: strparser: fix skb_head leak in strp_abort_strp()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: strparser: fix skb_head leak in strp_abort_strp()\n\nWhen the stream parser is aborted, for example after a message assembly timeout,\nit can still hold a reference to a partially assembled message in\nstrp-\u003eskb_head.\n\nThat skb is not released in strp_abort_strp(), which leaks the partially\nassembled message and can be triggered repeatedly to exhaust memory.\n\nFix this by freeing strp-\u003eskb_head and resetting the parser state in the\nabort path. Leave strp_stop() unchanged so final cleanup still happens in\nstrp_done() after the work and timer have been synchronized.","modified":"2026-06-05T18:29:40.002733186Z","published":"2026-05-27T12:59:09.526Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46102.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/19ca9475f18f991735f98a22e735c43e95e6298d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5327dad2ffe9c1b49881dd6d51ff3c6893847568"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56082f442023db9be1a5a29d4ee361de4017c0b7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a470ed71c906cc8cbad0d74c9942216698911f8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2e57695ec9ff9d42f23de70f3805199153d007b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d6668ce0e78d23eabecef9a6bc4f0f739cb28ad3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9ae00490d474757c0f9c65073de83e6bb1e5a00"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe72340daaf1af588be88056faf98965f39e6032"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46102.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46102"},{"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":"43a0c6751a322847cb6fa0ab8cbf77a1d08bfc0a"},{"fixed":"d6668ce0e78d23eabecef9a6bc4f0f739cb28ad3"},{"fixed":"a470ed71c906cc8cbad0d74c9942216698911f8b"},{"fixed":"c2e57695ec9ff9d42f23de70f3805199153d007b"},{"fixed":"e9ae00490d474757c0f9c65073de83e6bb1e5a00"},{"fixed":"5327dad2ffe9c1b49881dd6d51ff3c6893847568"},{"fixed":"19ca9475f18f991735f98a22e735c43e95e6298d"},{"fixed":"56082f442023db9be1a5a29d4ee361de4017c0b7"},{"fixed":"fe72340daaf1af588be88056faf98965f39e6032"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46102.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.9.0"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46102.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
