Описание
In the Linux kernel, the following vulnerability has been resolved:
scsi: message: mptlan: Fix use after free bug in mptlan_remove() due to race condition
mptlan_probe() calls mpt_register_lan_device() which initializes the &priv->post_buckets_task workqueue. A call to mpt_lan_wake_post_buckets_task() will subsequently start the work.
During driver unload in mptlan_remove() the following race may occur:
CPU0 CPU1
mptlan_remove() | free_netdev() | kfree(dev); | | | dev->mtu | //use
Fix this by finishing the work prior to cleaning up in mptlan_remove().
[mkp: we really should remove mptlan instead of attempting to fix it]
