CVE-2026-98346: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't get the radio mask for netdev-less wdevs cfg80211_calculate_bi_data() calls rdev_get_radio_mask() with wdev->netdev, which can be NULL and then crashes in mac80211. To avoid that, invert the order of checks since wdev->netdev is always valid for beaconing interfaces.

Affected products

• Linux Linux: from 6.11, before 6.12.112 (fixed in 6.12.112); from 6.13, before 6.18.54 (fixed in 6.18.54); from 6.19, before 7.2.8 (fixed in 7.2.8)
