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 (EPSS)

2.34% probability of exploitation in the next 30 days, higher than 84% of all scored CVEs.
