From: Siddh Raman Pant <code(a)siddh.me> stable inclusion from stable-v4.19.258 commit d9eb37db6a28b59a95a3461450ee209654c5f95b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG9HM CVE: CVE-2022-49942 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 15bc8966b6d3a5b9bfe4c9facfa02f2b69b1e5f0 upstream. When we are not connected to a channel, sending channel "switch" announcement doesn't make any sense. The BSS list is empty in that case. This causes the for loop in cfg80211_get_bss() to be bypassed, so the function returns NULL (check line 1424 of net/wireless/scan.c), causing the WARN_ON() in ieee80211_ibss_csa_beacon() to get triggered (check line 500 of net/mac80211/ibss.c), which was consequently reported on the syzkaller dashboard. Thus, check if we have an existing connection before generating the CSA beacon in ieee80211_ibss_finish_csa().
