Description

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

|mpt_lan_post_receive_buckets_work() 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]
