In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix kthread worker destruction in polling mode Fix the cleanup order in polling mode (irq work_list)) and WARN_ON(!list_empty(&worker->delayed_work_list)). The original code called kthread_destroy_worker() before hrtimer_cancel(), creating a race condition where the timer could fire during worker destruction and queue new work, triggering the WARN_ON. This causes the following warning on every module unload in polling mode: ------------[ cut here ]------------ WARNING: CPU: 2 PID: 1034 at kernel/kthread.c:1430 kthread_destroy_worker+0x84/0x98 Modules linked in: wave5(-) rpmsg_ctrl rpmsg_char ... Call trace: kthread_destroy_worker+0x84/0x98 wave5_vpu_remove+0xc8/0xe0 [wave5] platform_remove+0x30/0x58 ... ---[ end trace 0000000000000000 ]---
