  "description": "In the Linux kernel, the following vulnerability has been resolved:  binder: fix UAF in binder_free_transaction()  In binder_free_transaction(), the t-\u003Eto_proc is read under the t-\u003Elock. However, once the t-\u003Elock is dropped, the to_proc can die in parallel. This leads to a use-after-free error when we attempt to acquire its inner lock right afterwards:    ==================================================================   BUG: KASAN: slab-use-after-free in _raw_spin_lock\u002B0xe4/0x1a0   Write of size 4 at addr ffff00001125da70 by task B/672    CPU: 20 UID: 0 PID: 672 Comm: B Not tainted 7.1.0-rc6-00284-g8e65320d91cd #4 PREEMPT   Hardware name: linux,dummy-virt (DT)   Call trace:    _raw_spin_lock\u002B0xe4/0x1a0    binder_free_transaction\u002B0x8c/0x320    binder_send_failed_reply\u002B0x21c/0x2f8    binder_thread_release\u002B0x488/0x7e0    binder_ioctl\u002B0x12c0/0x29a0   [...]    Allocated by task 675:    __kmalloc_cache_noprof\u002B0x174/0x444    binder_open\u002B0x118/0xb70    do_dentry_open\u002B0x374/0x1040    vfs_open\u002B0x58/0x3bc   [...]    Freed by task 212:    __kasan_slab_free\u002B0x58/0x80    kfree\u002B0x1a0/0x4a4    binder_proc_dec_tmpref\u002B0x32c/0x5e0    binder_deferred_func\u002B0xc48/0x104c    process_one_work\u002B0x53c/0xbc0   [...]   ==================================================================  To prevent this, pin the target thread (t-\u003Eto_thread) to guarantee the target process remains alive.
