CVE-2026-97600

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.
