CVE-2021-39798

Name of the Vulnerable Software and Affected Versions Android versions Android-12 through Android-12L

Description The issue is related to a missing bounds check in the Bitmap createFromParcel function of Bitmap.cpp, which could lead to arbitrary code execution. This might result in local escalation of privilege, requiring User execution privileges. No user interaction is needed for exploitation.

Recommendations For Android versions Android-12 through Android-12L, consider restricting access to the Bitmap createFromParcel function until a patch is available. As a temporary workaround, avoid using the Bitmap createFromParcel function to minimize the risk of exploitation.
