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] netlinkupdatesocketmc+0x3c/0xc0 LR [c000000000c0f764] _netlinkclearmulticastusers+0x74/0xc0 Call Trace: _netlinkclearmulticastusers+0x74/0xc0 genlunregister_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.
