CVE-2023-53725

Kernel resource leak via incomplete probe cleanup

Published Oct 22, 2025 · Updated Oct 22, 2025

Memory leak in the Cadence TTC clocksource driver in Linux allows attackers to cause unspecified impact via unspecified vectors. In ttc_timer_probe, three failure exits after of_iomap leave timer_baseaddr mapped, and clock references for clk_ce and clk_cs also lack cleanup. The condition is reached during Cadence TTC device probing; the published record does not identify an attacker-controlled trigger or a consequence beyond retained kernel resources.
