Summary
In the Linux kernel, the following vulnerability has been resolved: perf: arm-ni: Unregister PMUs on probe failure When a resource allocation fails in one clock domain of an NI device, we need to properly roll back all previously registered perf PMUs in other clock domains of the same device. Otherwise, it can lead to kernel panics.
