Summary

In s_decode_vui_param of fw_hevc_dec_header.c, there is a possible out-of-bounds write due to a logic error in the code. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.

Risk Assessment

The vulnerability may enable remote code execution on the device, potentially resulting in full system compromise. The lack of required user interaction increases the risk of widespread exploitation.

Recommendation

Immediately install available security patches for the affected component. Until patches are deployed, limit exposure of services decoding HEVC streams.
