That is forbidden:\ndo_task_dead() calls __schedule(), which has a comment saying \"WARNING:\nmust be called with preemption disabled!\".\n\nIf an oopsing task is preempted in do_task_dead(), between becoming\nTASK_DEAD and entering the scheduler explicitly, bad things happen:\nfinish_task_switch() assumes that once the scheduler has switched away\nfrom a TASK_DEAD task, the task can never run again and its stack is no\nlonger needed; but that assumption apparently doesn\u0027t hold if the dead\ntask was preempted (the SM_PREEMPT case).\n\nThis means that the scheduler ends up repeatedly dropping references on\nthe dead task\u0027s stack, which can lead to use-after-free or double-free\nof the entire task stack; in other words, two tasks can end up running\non the same stack, resulting in various kinds of memory corruption.\n\n(This does not just affect \"recursively oopsing\" tasks; it is enough to\noops once during task exit, for example in a file_operations::release\nhandler)",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL\n\nThe SCTP_SENDALL path in sctp_sendmsg() iterates ep-\u003easocs with\nlist_for_each_entry_safe(), which caches the next entry in @tmp before\nthe loop body runs. The body calls sctp_sendmsg_to_asoc(), which may\ndrop the socket lock inside sctp_wait_for_sndbuf().\n\nWhile the lock is dropped, another thread can SCTP_SOCKOPT_PEELOFF the\nassociation cached in @tmp, migrating it to a new endpoint via\nsctp_sock_migrate() (list_del_init() + list_add_tail() to\nnewep-\u003easocs), and optionally close the new socket which frees the\nassociation via kfree_rcu(). The cached @tmp can also be freed by a\nnetwork ABORT for that association, processed in softirq while the\nlock is dropped.\n\nsctp_wait_for_sndbuf() revalidates @asoc (the current entry) on re-lock\nvia the \"sk != asoc-\u003ebase.sk\" and \"asoc-\u003ebase.dead\" checks, but nothing\nrevalidates @tmp.
