CVE-2022-20022

Status: ModifiedMedium (6.5)—

In Bluetooth, there is a possible link disconnection due to bluetooth does not properly handle a connection attempt from a host with the same BD address as the currently connected BT host. This could lead to remote denial of service of bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06198578; Issue ID: ALPS06198578.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
