The timer callback may still be running and can\nrearm itself, resulting in a use-after-free.\n\nUse timer_shutdown_sync() to wait for the callback and prevent further\nrearming. Do this unconditionally because ss_en may be changed after\nthe timer is armed.\n\nMove timer_setup() into init_realtek_cr() so the timer is initialized\nbefore any failure path can invoke the destructor.\n\nFound by static analysis.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/4ffee1aebb0c0ffcda9faffd17834ea9b00d42cc","tags":[]},{"url":"https://git.kernel.org/stable/c/7c4e2f964c65dea4ea22386799d5fb10ef1e3e54","tags":[]},{"url":"https://git.kernel.org/stable/c/cae9dbba6adae21a04a3bd045e07b489847ff2c6","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
