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: 2024-05-21T14:35:58.434Z\n\ud83d\udccf Modified: 2025-05-04T07:09:14.989Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/99779c9d9ffc7775da6f7fd8a7c93ac61657bed5\n2. https://git.kernel.org/stable/c/4e2a0848ea2cab0716d46f85a8ccd5fa9a493e51\n3. https://git.kernel.org/stable/c/c471569632654e57c83512e0fc1ba0dbb4544ad6\n4. https://git.kernel.org/stable/c/a7a7b2848312cc4c3a42b6e42a8ab2e441857aba\n5. https://git.kernel.org/stable/c/bdf5334250c69fabf555b7322c75249ea7d5f148\n6. https://git.kernel.org/stable/c/a7f7c42e31157d1f0871d6a8e1a0b73a6b4ea785\n7. https://git.kernel.org/stable/c/2f958b6f6ba0854b39be748d21dfe71e0fe6580f\n8. https://git.kernel.org/stable/c/5b991df8881088448cb223e769e37cab8dd40706\n9. https://git.kernel.org/stable/c/34e7434ba4e97f4b85c1423a59b2922ba7dff2ea", "creation_timestamp": "2025-05-04T07:17:47.000000Z"} 2025-05-04T07:17:47+00:00
