In multiple locations of avrc, there is a possible leak of heap data due to uninitialized data. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

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).
