| VULNERABILITY DETAILS |
This vulnerability allows local attackers to disclose sensitive information on affected installations of Google Android. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the fts_driver_test_write function. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before reading from memory. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute code in the context of the kernel. |
