CVE-2026-98325
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: set up the TX info early to fix failure paths The previous commit 2c51457d930f ("wifi: mac80211: free ack status frame on TX header build failure") cleaned up the leak, but still left the code a bit messy and the failed SKB didn't get reported to userspace. Fix this up by initialising skb->cb[] earlier, which allows using ieee80211_free_txskb() and therefore reports it for the failure in ieee80211_build_hdr(), and unifies the ieee80211_skb_resize() failure path with it.
