Live › vulnerability › CVE-2026-98535
Go to dashboardThe Freescale FMan driver in the Linux kernel gets a clock from the device tree and reads its rate but never releases the reference, so the clock reference count leaks. The sources describe a resource leak and do not mention a way for an attacker to gain access or run code.
Summary written from the sources below. Check the originals before acting.

Systems running a Linux kernel with the Freescale FMan (fsl/fman) network driver, typically Freescale/NXP QorIQ based boards, where the device tree defines FMan nodes. Systems without this hardware are not affected. The sources do not say whether the leak can be triggered by an attacker.

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.
