Description

net: Fix an unsafe loop on the list

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

net: Fix an unsafe loop on the list

The kernel may crash when deleting a genetlink family if there are still

listeners for that family:

Oops: Kernel access of bad area, sig: 11 [#1]

...

NIP [c000000000c080bc] netlink_update_socket_mc+0x3c/0xc0

LR [c000000000c0f764] __netlink_clear_multicast_users+0x74/0xc0

Call Trace:

__netlink_clear_multicast_users+0x74/0xc0

genl_unregister_family+0xd4/0x2d0

Change the unsafe loop on the list to a safe one, because inside the

loop there is an element removal from this list.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
