Summary
The Clear Channel Assessment (CCA) algorithm in the IEEE 802.11 wireless protocol, when using DSSS transmission encoding, allows remote attackers to cause a denial of service via a certain RF signal that causes a channel to appear busy (aka "jabber"), which prevents devices from transmitting data.
Exploit prediction
2.34% chance of exploitation in the next 30 days, higher than 83% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
