CVE-2022-20566
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
Summary
In l2cap_chan_put of l2cap_core, there is a possible use-after-free due to improper locking. This could lead to local privilege escalation without additional execution privileges or user interaction.
Risk Assessment
A local attacker could exploit this vulnerability to escalate privileges, potentially leading to full device compromise.
Recommendation
Install Android kernel updates that include the fix for this issue and monitor devices for suspicious activity.
