Description
A vulnerability in the Linux kernel's mac80211 wifi subsystem related to the setup of TX info has been fixed. The issue involved failure paths where the failed socket buffer (SKB) was not properly reported to userspace, potentially causing inconsistent behavior. The fix involves initializing skb->cb[] earlier to unify failure handling and ensure proper reporting of transmission failures.
