  - team: fix null-ptr-deref when team device type is changed Get a null-ptr-deref bug as follows with     reproducer [1]. BUG: kernel NULL pointer dereference, address: 0000000000000228 ... RIP:

That is incorrect and will trigger null-ptr-deref for vlan->real_dev in     vlan_dev_hard_header() because team device is not a vlan device. Cache eth_header_ops in team_setup(),     then assign cached header_ops to header_ops of team net device when its type is changed from non-ether to     ether to fix the bug. (CVE-2023-52574)

Note that Nessus relies on the presence of the package as reported by the vendor.
