Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
