Overview

CVE-2026-90350 is a known-severity vulnerability. It was published on September 17, 2026.

Technical description

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

wifi: mt76: reject out-of-range link ids in mt76_vif_link()

mt76_vif_link() indexes mvif->link[] without validating link_id, but

callers pass mvif->deflink_id / msta->deflink_id, which hold

IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added.

Since IEEE80211_MLD_MAX_NUM_LINKS is 15, that reads one element past the

end of the array, aliasing mt76_vif_data.offchannel_link.

Reachable via mt7996_set_tsf()/mt7996_offset_tsf() and

mt7996_net_fill_forward_path(). Bounds check link_id and return NULL,

matching mt7996_sta_link() and mt7996_sta_link_protected().

How can CyberStrike help with CVE-2026-90350?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-90350 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
