## Overview

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: use two-phase skb reclamation in ieee80211_do_stop()

Since '__dev_queue_xmit()' should be called with interrupts enabled,
the following backtrace:

ieee80211_do_stop()
 ...
 spin_lock_irqsave(&local->queue_stop_reason_lock, flags)
 ...
 ieee80211_free_txskb()
  ieee80211_report_used_skb()

     nl80211_frame_tx_status()

	      __netlink_deliver_tap_skb()
	       dev_queue_xmit()
	        __dev_queue_xmit() ; with IRQS disabled
 ...
 spin_unlock_irqrestore(&local->queue_stop_reason_lock, flags)

issues the warning (as reported by syzbot reproducer):

WARNING: CPU: 2 PID: 5128 at kernel/softirq.c:362 __local_bh_enable_ip+0xc3/0x120

Fix this by implementing a two-phase skb reclamation in
'ieee80211_do_stop()', where actual work is performed
outside of a section with interrupts disabled.

## Affected

- `linux_kernel >= 2.6.32, < 5.10.227`
- `linux_kernel >= 5.11, < 5.15.168`
- `linux_kernel >= 5.16, < 6.1.113`
- `linux_kernel >= 6.2, < 6.6.54`
- `linux_kernel >= 6.7, < 6.10.13`
- `linux_kernel >= 6.11, < 6.11.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.11.2`
