CVE-2016-0821 describes a vulnerability in the LIST_POISON feature of the Linux kernel, specifically affecting Android versions before 6.0.1 (March 2016 update). This flaw allows attackers to bypass a poison-pointer protection mechanism by exploiting the relationship between LIST_POISON and mmap_min_addr, leading to the use of uninitialized list entries. Rated as Medium severity (CVSS 5.5), it requires local access and low attack complexity to achieve high integrity impact, though confidentiality and availability are not affected. There is no evidence of active exploitation, public exploit code, or significant community discussion, despite some media coverage from SecurityWeek.
