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: 2024-05-21T14:35:59.761Z\n\ud83d\udccf Modified: 2025-05-04T07:09:17.214Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/9e161687855175334ca93c6c3ccb221731194479\n2. https://git.kernel.org/stable/c/a832ee2f2145f57443b2d565f8cb5490e8339f42\n3. https://git.kernel.org/stable/c/bcdd2be48edd8c6867fb44112cb8d18086beae29\n4. https://git.kernel.org/stable/c/89ce0b0747f319eb70f85bc820dcc43cebbd5417\n5. https://git.kernel.org/stable/c/c9172498d4d62c9b64e5fb37c1ee0343e65fe51b\n6. https://git.kernel.org/stable/c/e759ff76ebbbfcdcf83b6634c54dc47828573d8b\n7. https://git.kernel.org/stable/c/b58d246a058ae88484758cd4ab27b3180fd5ecf8\n8. https://git.kernel.org/stable/c/d1fb12412874c94ad037e11d0ecdd1140a439297\n9. https://git.kernel.org/stable/c/1c72e6ab66b9598cac741ed397438a52065a8f1f", "creation_timestamp": "2025-05-04T07:17:45.000000Z"}
