Details

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

bonding: stop the device in bondsetupby_slave()

Commit 9eed321cde22 ("net: lapbether: only support ethernet devices") has been able to keep syzbot away from net/lapb, until today.

In the following splat [1], the issue is that a lapbether device has been created on a bonding device without members. Then adding a non ARPHRD_ETHER member forced the bonding master to change its type.

The fix is to make sure we call devclose() in bondsetupbyslave() so that the potential linked lapbether devices (or any other devices having assumptions on the physical device) are removed.

A similar bug has been addressed in commit 40baec225765 ("bonding: fix panic on non-ARPHRD_ETHER enslave failure")
