CVE-2026-98182: wifi: mac80211: refuse to make a monitor active when it has no queue
Noroxi assessment
Priority: Monitor (action score 0/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
- Fixed version: Linux Linux 2b04d6556964ae9f89819b86a0a7801e39c3aae5, 46c223468537a05a404699771cd3e68532dab5e6, abe15e643e576459469867758ae9c586a7bab95d; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.
Low priority for now. Upgrade to Linux Linux 2b04d6556964ae9f89819b86a0a7801e39c3aae5, 46c223468537a05a404699771cd3e68532dab5e6, abe15e643e576459469867758ae9c586a7bab95d; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: refuse to make a monitor active when it has no queue A monitor interface only gets a TXQ if it's created active, and one can't be added later. Setting the flag on a down interface is still allowed, so the driver is handed a monitor with no queue. ath9k dereferences it: BUG: kernel NULL pointer dereference, address: 0000000000000066 RIP: 0010:ath_tx_node_init+0x49/0x170 [ath9k] ath9k_add_interface+0x10c/0x140 [ath9k] drv_add_interface+0x54/0x250 [mac80211] ieee80211_do_open+0x32f/0x800 [mac80211] Reached with CAP_NET_ADMIN by "iw dev X set monitor active" followed by "ip link set X up". RTNL is held, so netlink operations block behind it. Refuse the flag when there is no queue to give.
