https://notcve.org/view.php?id=CVE-2021-47321
In the Linux kernel, the following vulnerability has been resolved: watchdog: Fix possible use-after-free by calling del_timer_sync() This driver's remove path calls del_timer(). However, that function does not wait until the timer handler finishes. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling del_timer_sync(), which makes sure the timer handler has finished, and unable to re-schedule itself. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: perro guardián: solucione el posible use after free llamando a del_timer_sync(). La ruta de eliminación de este controlador llama a del_timer(). • https://git.kernel.org/stable/c/58606882ad8ec6c39e0f40344b922921ef94ab4d https://git.kernel.org/stable/c/ca96b8ea5e74956071154bdb456778cc3027e79f https://git.kernel.org/stable/c/8bec568d7518b1504a602ed5376bb322e4dbb270 https://git.kernel.org/stable/c/ecd620e0fb1ff7f78fdb593379b2e6938c99707a https://git.kernel.org/stable/c/db222f1477ad5692cd454709b714949807e5d111 https://git.kernel.org/stable/c/66ba9cf929b1c4fabf545bd4c18f6f64e23e46e4 https://git.kernel.org/stable/c/4c05dac488a660fe2925c047ecb119e7afaaeb1e https://git.kernel.org/stable/c/1a053c4d716898a53c2e31c574a70ea0c • CWE-416: Use After Free •
