Official Description

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

wifi: mac80211: drop stray 'static' from fast-RX rx_result

ieee80211_invoke_fast_rx() is documented as safe for parallel RX, but

its per-invocation rx_result is declared static. Concurrent callers then

share one instance and can overwrite each other's result between

ieee80211_rx_mesh_data() and the switch on res.

That can make a packet that was queued or consumed by

ieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make

a packet that should continue return as queued.

Make res an automatic variable so each invocation keeps its own result.

Technical Analysis

CVE-2026-46152 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
