It is\nthen not safe to access 't' after BR_TRANSACTION_PENDING_FROZEN errors\nas the transaction could have been consumed by the now thawed target.\n\nThis is the case for binder_netlink_report() which derreferences 't'\nafter a pending frozen error, as pointed out by the following KASAN\nreport:\n\n  ==================================================================\n  BUG: KASAN: slab-use-after-free in binder_netlink_report.isra.0+0x694/0x6c8\n  Read of size 8 at addr ffff00000f98ba38 by task binder-util/522\n\n  CPU: 4 UID: 0 PID: 522 Comm: binder-util Not tainted 6.19.0-rc6-00015-gc03e9c42ae8f #1 PREEMPT\n  Hardware name: linux,dummy-virt (DT)\n  Call trace:\n   binder_netlink_report.isra.0+0x694/0x6c8\n   binder_transaction+0x66e4/0x79b8\n   binder_thread_write+0xab4/0x4440\n   binder_ioctl+0x1fd4/0x2940\n   [...]\n\n  Allocated by task 522:\n   __kmalloc_cache_noprof+0x17c/0x50c\n   binder_transaction+0x584/0x79b8\n   binder_thread_write+0xab4/0x4440\n   binder_ioctl+0x1fd4/0x2940\n   [...]\n\n  Freed by task 488:\n   kfree+0x1d0/0x420\n   binder_free_transaction+0x150/0x234\n   binder_thread_read+0x2d08/0x3ce4\n   binder_ioctl+0x488/0x2940\n   [...]\n  ==================================================================\n\nInstead, make a transaction copy so the data can be safely accessed by\nbinder_netlink_report() after a pending frozen error.
