Name of the Vulnerable Software and Affected Versions Android kernel

Description The issue is related to an incorrect bounds check in the ConvertToHalMetadata function of aidl utils.cc, which could lead to a possible out of bounds read. This might result in local information disclosure, requiring System execution privileges for exploitation. No user interaction is needed for exploitation.

Recommendations For Android kernel, consider applying a patch that fixes the incorrect bounds check in the ConvertToHalMetadata function of aidl utils.cc as a permanent solution. As a temporary workaround, restrict access to sensitive system information to minimize the risk of exploitation.
