Public exploitNot knownno public code found

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

serial: ma35d1: Fix clock reference leak in ma35d1serial_probe()

of_clk_get() returns a clock with a reference that has to be released with clk_put(). ma35d1serial_probe() never does that, so the reference is leaked on the probe error paths and also when the port is removed.

Release it on the error paths and in ma35d1serial_remove().

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: 0.17 %
Percentile among all scored CVEs: 6
Score date: 10/20/2026

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).
