In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: ocb: don't leave if not joined
If there's no OCB state, don't ask the driver/mac80211 to
leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check.

kernel: wifi: cfg80211: ocb: don't leave if not joined

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. When handling OCB (Outside the Context of a BSS) mode, the kernel may attempt to leave an OCB network even when not joined, which could cause driver confusion or unexpected behavior. This is a logic error in state management.
Statement: This is a minor logic fix in the WiFi cfg80211 subsystem for OCB mode, which is used in vehicular networking (802.11p/DSRC). The issue does not cause a crash but could le
