The body calls sctp_sendmsg_to_asoc(), which may drop the socket lock inside sctp_wait_for_sndbuf().  While the lock is dropped, another thread can SCTP_SOCKOPT_PEELOFF the association cached in @tmp, migrating it to a new endpoint via sctp_sock_migrate() (list_del_init() + list_add_tail() to newep->asocs), and optionally close the new socket which frees the association via kfree_rcu().  The cached @tmp can also be freed by a network ABORT for that association, processed in softirq while the lock is dropped.  sctp_wait_for_sndbuf() revalidates @asoc (the current entry) on re-lock via the \"sk != asoc->base.sk\" and \"asoc->base.dead\" checks, but nothing revalidates @tmp.  After a successful return, the iterator advances to the stale @tmp, yielding either a use-after-free (if the peeled socket was closed) or a list-walk onto the new endpoint's list head (type confusion of &newep->asocs as a struct sctp_association *).  Both are reachable from CapEff=0; the type-confusion path gives controlled indirect call via the outqueue.sched->init_sid pointer.  Fix by re-deriving @tmp from @asoc after sctp_sendmsg_to_asoc() returns.  @asoc is known to still be on ep->asocs at that point: the only callers that list_del an association from ep->asocs are sctp_association_free() (which sets asoc->base.dead) and sctp_assoc_migrate() (which changes asoc->base.sk), and sctp_wait_for_sndbuf() checks both under the lock before any successful return; a tripped check propagates as err \u003C 0 and the loop bails before the re-derive.  The SCTP_ABORT path in sctp_sendmsg_check_sflags() returns 0 and the loop hits 'continue' before sctp_sendmsg_to_asoc() is ever called, so the @tmp cached by list_for_each_entry_safe() still covers the lock-held free that ba59fb027307 (\"sctp: walk the list of asoc safely\") was added for.",null,[],[],[],[14],{"_key":15},"CVE-2026-46227",[],[],[],"2026-05-28T10:16:38.317Z","2026-07-05T20:00:54.228508284Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2026-46227",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},7.8,"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H",9.8,4.6,[40,64],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,50,51,55,58,61],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":52,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":53,"version_end_type":54,"fixed_in":9},"lt5_10_259_1","5.10.259-1","excluding",{"version":56,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":57,"version_end_type":54,"fixed_in":9},"lt6_1_176_1","6.1.176-1",{"version":59,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":60,"version_end_type":54,"fixed_in":9},"lt6_12_90_1","6.12.90-1",{"version":62,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":63,"version_end_type":54,"fixed_in":9},"lt7_0_9_1","7.0.9-1",{"ecosystem":41,"name":65,"vendor":43,"product":65,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":65,"source":9,"versions":66},"linux-6.1",[67],{"version":68,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":69,"version_end_type":54,"fixed_in":9},"lt6_1_176_1~deb11u1","6.1.176-1~deb11u1"]
