Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: power: supply: rk817: Fix node refcount leak Dan Carpenter reports that the Smatch static checker warning has found that there is another refcount leak in the probe function.
