CVE-2026-46152: wifi: mac80211: drop stray 'static' from fast-RX rx_result
Noroxi assessment
Priority: Monitor (action score 35/100)
- 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: 0.23% (FIRST EPSS).
- Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 03584528bfffb195e384698af9148b94e42e3f14, 1739fc31b4de06c5c78ce0741182770fb079091e, 3ef44f96ccc3e06e059dec57842e366f0c4b1893; azl3 kernel 6.6.139.1-1 on Azure Linux 3.0 6.6.141.1-1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 03584528bfffb195e384698af9148b94e42e3f14, 1739fc31b4de06c5c78ce0741182770fb079091e, 3ef44f96ccc3e06e059dec57842e366f0c4b1893; azl3 kernel 6.6.139.1-1 on Azure Linux 3.0 6.6.141.1-1 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
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.
