CVE-2026-98346

Estado: RecibidaSin puntuar—

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.
