A fix has been applied to the Linux kernel to address this issue. Users should update to the patched kernel versions to remediate the vulnerability. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's remoteproc SCP driver caused a device reference leak when a lookup failed. The issue was fixed by ensuring the reference to the SCP device is properly dropped if the driver data lookup fails before the driver is bound.
