Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2024-002913)
medium Nessus Plugin ID 341427
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2024-002913 advisory.In the Linux kernel, the following vulnerability has been resolved:
net: fix possible store tearing in neigh_periodic_work()
While looking at a related syzbot report involving neigh_periodic_work(), I found that I forgot to add an annotation when deleting an RCU protected item from a list.
Readers use rcu_deference(*np), we need to use either rcu_assign_pointer() or WRITE_ONCE() on writer side to prevent store tearing.
I use rcu_assign_pointer() to have lockdep support, this was the choice made in neigh_flush_dev().
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel package.See Also
