However, the reference in the +active task would remain. So once the active rekeying progresses and +the collision is resolved, that dangling pointer would get dereferenced +for an indirect method call. This happens via the `get_lower_nonce` +function pointer of the `child_create_t` instance in the private task +struct. So besides having to be authenticated, an attacker has to get +two indirections right to exploit this flaw for a potential RCE. +Otherwise, the effects are a crash or basically undefined behavior +triggered by the method call. + +By passing whether the passive task is done (and would get destroyed), +the active tasks can properly clear the held reference. + +Note that this patch includes another fix for a state change during +Child SA rekeying that's included in 6.1.0 (4611f41b1e14 ("child-rekey: +Only reset state of SAs not actively rekeyed if passive rekeying +fails")). + +Fixes: d2b2e1b3fae8 ("ikev2: Make CHILD_SAs properly trackable during rekey collisions") +Fixes: ca3e6d2d144e ("ike-rekey: Support IKE_SA rekeying with multiple key exchanges") +Fixes: CVE-2026-78133 + +CVE: CVE-2026-78133 +Upstream-Status: Backport [https://github.com/strongswan/strongswan/commit/eb615b452539461d57503f50041f01773c1ccf86] + +Signed-off-by: Ankur Tyagi +--- + src/libcharon/sa/ikev2/task_manager_v2.c | 13 +- + src/libcharon/sa/ikev2/tasks/child_rekey.c | 47 ++++-- + src/libcharon/sa/ikev2/tasks/child_rekey.h | 3 +- + src/libcharon/sa/ikev2/tasks/ike_rekey.c | 40 +++-- + src/libcharon/sa/ikev2/tasks/ike_rekey.h | 3 +- + src/libcharon/tests/suites/test_child_rekey.c | 136 ++++++++++++++++ + src/libcharon/tests/suites/test_ike_rekey.c | 147 ++++++++++++++++++ + 7 files changed, 361 insertions(+), 28 deletions(-) + +diff --git a/src/libcharon/sa/ikev2/task_manager_v2.c b/src/libcharon/sa/ikev2/task_manager_v2.c +index 0f3b937..5a19ce8 100644 +--- a/src/libcharon/sa/ikev2/task_manager_v2.c ++++ b/src/libcharon/sa/ikev2/task_manager_v2.c +@@ -927,7 +927,8 @@ static status_t process_response(private_task_manager_t *this, + * Handle exchange collisions, returns TRUE if the given passive task was + * adopted by the active task and the task manager lost control over it. + */ +-static bool handle_collisions(private_task_manager_t *this, task_t *task) ++static bool handle_collisions(private_task_manager_t *this, task_t *task, ++ bool done) + { + enumerator_t *enumerator;
