CVE-2024-43831

Local denial of service via invalid decoder VSI

Published Aug 17, 2024 · Updated May 11, 2026

Denial of service in the MediaTek video decoder in affected Linux kernels starting at 4.10 allows local users to interrupt service. The vpu_dec_init function returns after vcodec_vpu_send_msg without rejecting an error or null vpu->vsi pointer, leaving later decoder operations to use an invalid VSI. Local low-privileged access to the MediaTek video-decoder path is required, and the published impact is limited to availability.
