CVE-2024-57991

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

wifi: rtw89: chan: fix soft lockup in rtw89entityrecalcmgntroles()

During rtw89entityrecalcmgntroles(), there is a normalizing process which will re-order the list if an entry with target pattern is found. And once one is found, should have aborted the listforeachentry. But, break just aborted the inner for-loop. The outer listforeachentry still continues. Normally, only the first entry will match the target pattern, and the re-ordering will change nothing, so there won't be soft lockup. However, in some special cases, soft lockup would happen.

Fix it by goto fill to break from the listforeach_entry.

The following is a sample of kernel log for this problem.
