CVE-2023-53605

Local service interruption via display-context memory leak

Published Oct 4, 2025 · Updated Oct 4, 2025

Memory leak in Linux kernel AMD display code allows local users to exhaust memory through display-context initialization. In dc_construct_ctx(), failure of dc_perf_trace_create() returns without freeing the newly allocated dc_ctx object. The published record establishes local low-privilege access and availability impact, but does not disclose how attackers trigger the allocation failure.
