Incorrect Authorization in Qualcomm GPU micronode command interface
CVE-2025-21480 is an incorrect authorization vulnerability affecting multiple Qualcomm chipsets in the graphics/GPU component. The provided content describes it as memory corruption caused by unauthorized command execution in the GPU micronode while executing a specific sequence of commands. The flaw appears to stem from failure to correctly enforce access control on a GPU command path, allowing unauthorized commands to reach privileged GPU microcode/micronode functionality. Successful triggering can corrupt memory buffers and destabilize adjacent memory structures in the GPU driver or firmware path. Qualcomm and multiple secondary sources also characterize the issue as an authorization bypass in the GPU interface and note that it affects multiple Qualcomm chipsets, with indications from Google Threat Analysis Group that it may have been used in limited, targeted exploitation.
