  "description": "In the Linux kernel, the following vulnerability has been resolved:  rust_binder: remove spin_lock() in rust_shrink_free_page()  When forward-porting Rust Binder to 6.18, I neglected to take commit fb56fdf8b9a2 (\u0022mm/list_lru: split the lock to per-cgroup scope\u0022) into account, and apparently I did not end up running the shrinker callback when I sanity tested the driver before submission. This leads to crashes like the following:  \t============================================ \tWARNING: possible recursive locking detected \t6.18.0-mainline-maybe-dirty #1 Tainted: G          IO \t-------------------------------------------- \tkswapd0/68 is trying to acquire lock: \tffff956000fa18b0 (\u0026l-\u003Elock){\u002B.\u002B.}-{2:2}, at: lock_list_lru_of_memcg\u002B0x128/0x230  \tbut task is already holding lock: \tffff956000fa18b0 (\u0026l-\u003Elock){\u002B.\u002B.}-{2:2}, at: rust_helper_spin_lock\u002B0xd/0x20  \tother info that might help us debug this: \t Possible unsafe locking scenario:  \t       CPU0 \t       ---- \t  lock(\u0026l-\u003Elock); \t  lock(\u0026l-\u003Elock);  \t *** DEADLOCK ***  \t May be due to missing lock nesting notation  \t3 locks held by kswapd0/68: \t #0: ffffffff90d2e260 (fs_reclaim){\u002B.\u002B.}-{0:0}, at: kswapd\u002B0x597/0x1160 \t #1: ffff956000fa18b0 (\u0026l-\u003Elock){\u002B.\u002B.}-{2:2}, at: rust_helper_spin_lock\u002B0xd/0x20 \t #2: ffffffff90cf3680 (rcu_read_lock){....}-{1:2}, at: lock_list_lru_of_memcg\u002B0x2d/0x230  To fix this, remove the spin_lock() call from rust_shrink_free_page().",
