Public exploitNot knownno public code found

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

fsl/fman: Fix clk reference leak in read_dts_node()

of_clk_get() returns a clock with its reference count incremented, but read_dts_node() only uses it to read the rate and never calls clk_put(). The clock is not stored anywhere, so the reference cannot be released later either.

Release the clock once its rate has been read, which also covers the error path taken when the rate is zero.

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: 0.22 %
Percentile among all scored CVEs: 12
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).
