CVE-2023-53725

Status: DeferredUnscored—

In the Linux kernel, the following vulnerability has been resolved:

clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe

Smatch reports: drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe() warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516.

timer_baseaddr may have the problem of not being released after use, I replaced it with the devm_of_iomap() function and added the clk_put() function to cleanup the "clk_ce" and "clk_cs".

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.21%
Percentile among all scored CVEs: 10
Score date: 10/6/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
