Name of the Vulnerable Software and Affected Versions Android CAF-сборки (affected versions not specified)

Description The issue is related to the use of memory after it has been freed. This can be exploited by a remote attacker to impact the confidentiality, integrity, and availability of protected information. The problem arises in the mdss fb copy destscaler data() function, where the ds data[i].scale variable may still point to a user-provided address, potentially allowing an attacker to free an arbitrary address. If an error occurs, this could lead to the use of memory after it has been freed.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
