CVE-2024-57991

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: rtw89: chan: fix soft lockup in rtw89_entity_recalc_mgnt_roles()<br /> <br /> During rtw89_entity_recalc_mgnt_roles(), there is a normalizing process<br /> which will re-order the list if an entry with target pattern is found.<br /> And once one is found, should have aborted the list_for_each_entry. But,<br /> `break` just aborted the inner for-loop. The outer list_for_each_entry<br /> still continues. Normally, only the first entry will match the target<br /> pattern, and the re-ordering will change nothing, so there won&amp;#39;t be<br /> soft lockup. However, in some special cases, soft lockup would happen.<br /> <br /> Fix it by `goto fill` to break from the list_for_each_entry.<br /> <br /> The following is a sample of kernel log for this problem.<br /> <br /> watchdog: BUG: soft lockup - CPU#1 stuck for 26s! [wpa_supplicant:2055]<br /> [...]<br /> RIP: 0010:rtw89_entity_recalc ([...] chan.c:392 chan.c:479) rtw89_core<br /> [...]
