NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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

net: netpoll: initialize work queue before error checks

Prevent a kernel warning when netconsole setup fails on devices with IFF_DISABLE_NETPOLL flag. The warning (at kernel/workqueue.c:4242 in __flush_work) occurs because the cleanup path tries to cancel an uninitialized work queue.

When __netpoll_setup() encounters a device with IFF_DISABLE_NETPOLL, it fails early and calls skb_pool_flush() for cleanup. This function calls cancel_work_sync(&np->refill_wq), but refill_wq hasn't been initialized yet, triggering the warning.

Move INIT_WORK() to the beginning of __netpoll_setup(), ensuring the work queue is properly initialized before any potential failure points. This allows the cleanup path to safely cancel the work queue regardless of where the setup fails.
