CVE-2025-68762

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: netpoll: initialize work queue before error checks<br /> <br /> Prevent a kernel warning when netconsole setup fails on devices with<br /> IFF_DISABLE_NETPOLL flag. The warning (at kernel/workqueue.c:4242 in<br /> __flush_work) occurs because the cleanup path tries to cancel an<br /> uninitialized work queue.<br /> <br /> When __netpoll_setup() encounters a device with IFF_DISABLE_NETPOLL,<br /> it fails early and calls skb_pool_flush() for cleanup. This function<br /> calls cancel_work_sync(&amp;np-&gt;refill_wq), but refill_wq hasn&amp;#39;t been<br /> initialized yet, triggering the warning.<br /> <br /> Move INIT_WORK() to the beginning of __netpoll_setup(), ensuring the<br /> work queue is properly initialized before any potential failure points.<br /> This allows the cleanup path to safely cancel the work queue regardless<br /> of where the setup fails.
