## Technical details

A Use-After-Free (CWE-416) vulnerability exists in Qualcomm Snapdragon firmware due to improper synchronization during device input/output control (IOCTL) operations. Specifically, the flaw occurs when mapping and unmapping persistent memory buffers. A local attacker with low privileges can trigger this race condition, leading to memory corruption. Successful exploitation could allow an attacker to achieve arbitrary code execution or escalate privileges, though the attack requires specific timing and user interaction. Patches are typically distributed via OEM security updates.
