Mô tả CVE
In the Linux kernel, the following vulnerability has been resolved:
ieee802154: cc2520: fix FIFOP work use-after-free
The FIFOP interrupt handler queues cc2520_fifop_irqwork. On removal,
cc2520_remove() only flushes the work. The devm-managed FIFOP IRQ
remains active until after ->remove() returns and can queue the work
again after that flush, allowing it to run after the private data is
released.
Disable the work with disable_work_sync() instead of flushing it, so
the handler can no longer queue it once removal begins. Destroy the
buffer mutex last, since the worker and the stop callback invoked
through ieee802154_unregister_hw() both take it.
Found by an in-house static analysis tool.
