Description OSIDB Bzimport 2025-12-30 13:09:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev()

The kfree() should be called when of_irq_get_byname() fails or
devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(),
otherwise there will be a memory leak, so add kfree() to fix it.
