"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtlwifi: pci: fix possible use-after-free caused by unfinished irq_prepare_bcn_tasklet\n\nThe irq_prepare_bcn_tasklet is initialized in rtl_pci_init() and\nscheduled when RTL_IMR_BCNINT interrupt is triggered by hardware.\nBut it is never killed in rtl_pci_deinit(). When the rtlwifi card\nprobe fails or is being detached, the ieee80211_hw is deallocated.\nHowever, irq_prepare_bcn_tasklet may still be running or pending,\nleading to use-after-free when the freed ieee80211_hw is accessed\nin _rtl_pci_prepare_bcn_tasklet().\n\nSimilar to irq_tasklet, add tasklet_kill() in rtl_pci_deinit() to\nensure that irq_prepare_bcn_tasklet is properly terminated before\nthe ieee80211_hw is released.\n\nThe issue was identified through static analysis."
