However, that function\ndoes not wait until the timer handler finishes. This means that the\ntimer handler may still be running after the driver's remove function\nhas finished, which would result in a use-after-free.\n\nFix by calling del_timer_sync(), which makes sure the timer handler\nhas finished, and unable to re-schedule itself.\n\ud83d\udccf Published: 2024-05-21T14:35:59.097Z\n\ud83d\udccf Modified: 2025-05-04T07:09:16.037Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/49331c07ef0f8fdfa42b30ba6a83a657b29d7fbe\n2. https://git.kernel.org/stable/c/54ff3202928952a100c477248e65ac6db01258a7\n3. https://git.kernel.org/stable/c/7867ddc5f3de7f289aee63233afc0df4b62834c5\n4. https://git.kernel.org/stable/c/5f2818185da0fe82a932f0856633038b66faf124\n5. https://git.kernel.org/stable/c/3ecd228c636ee17c14662729737fa07242a93cb0\n6. https://git.kernel.org/stable/c/b7ee9ae1e0cf55a037c4a99af2acc5d78cb7802d\n7. https://git.kernel.org/stable/c/61370ff07e0acc657559a8fac02551dfeb9d3020\n8. https://git.kernel.org/stable/c/ed7c3739d0a07e2ec3ccbffe7e93cea01c438cda\n9. https://git.kernel.org/stable/c/009fc857c5f6fda81f2f7dd851b2d54193a8e733", "creation_timestamp": "2025-05-04T07:17:46.000000Z"} 2025-05-04T07:17:46+00:00
