In the Linux kernel, the following vulnerability has been resolved:

wifi: rtlwifi: pci: fix possible use-after-free caused by unfinished irq_prepare_bcn_tasklet

The irq_prepare_bcn_tasklet is initialized in rtl_pci_init() and scheduled when RTL_IMR_BCNINT interrupt is triggered by hardware. But it is never killed in rtl_pci_deinit(). When the rtlwifi card probe fails or is being detached, the ieee80211_hw is deallocated. However, irq_prepare_bcn_tasklet may still be running or pending, leading to use-after-free when the freed ieee80211_hw is accessed in _rtl_pci_prepare_bcn_tasklet().

Similar to irq_tasklet, add tasklet_kill() in rtl_pci_deinit() to ensure that irq_prepare_bcn_tasklet is properly terminated before the ieee80211_hw is released.

The issue was identified through static analysis.
