Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists where dibs->lock is initialized by dibs dev add(), but a device may trigger interrupts before this call occurs. Specifically, ism probe() executes ism dev init() and request irq() prior to calling dibs dev add(). While dmb interrupts cannot occur at this stage, a GID event interrupt can, leading ism handle irq() to attempt to acquire dibs->lock unconditionally upon entry before any other inspections are performed.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
