+Subject: [PATCH] memstick: r592: Fix UAF bug in r592_remove due to race condition
+Git-commit: 63264422785021704c39b38f65a78ab9e4a186d7
+Patch-mainline: v6.4-rc1
+References: bsc#1211449
+
+In r592_probe, dev->detect_timer was bound with r592_detect_timer.
+In r592_irq function, the timer function will be invoked by mod_timer.
+
+If we remove the module which will call hantro_release to make cleanup,
+there may be a unfinished work. The possible sequence is as follows,
+which will cause a typical UAF bug.
+
+Fix it by canceling the work before cleanup in r592_remove.
