"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: serialize oplock close with pending break ownership\n\nclose may abort an in-flight oplock break while another breaker already\nholds an opinfo reference. Releasing pending_break wakes that waiter, but\nwithout serializing the close transition with bit acquisition it can become\na new break owner through the test_and_set_bit() fast path. It can then\noverwrite OPLOCK_CLOSING with OPLOCK_ACK_WAIT and continue a break for\na dying opinfo.\n\nMake OPLOCK_CLOSING terminal once the opinfo is removed from the inode\nlist. Serialize that transition, pending_break acquisition, and\nOPLOCK_ACK_WAIT setup with an opinfo state lock. A breaker which loses\nthe race releases its ownership and returns -ENOENT. Explicitly wake\npending_break waiters during close so they can observe the terminal state.\n\nAlso prevent ACK and timeout paths from replacing OPLOCK_CLOSING with\nOPLOCK_STATE_NONE."
