CVE-2022-20572
MediumCVSS 6.7Exploitation Probability (EPSS)
Low risk47th percentile - higher than 47% of all known CVEs
Summary
In the Android kernel, in verity_target of dm-verity-target.c, a missing permission check allows modification of read-only files. This could lead to local privilege escalation with System execution privileges. User interaction is not needed.
Risk Assessment
The risk includes privilege escalation, potentially allowing an attacker to gain control over the device or modify critical system files.
Recommendation
Apply kernel patches and update the Android system to the latest version to mitigate the vulnerability.
