Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the comedi subsystem, specifically within the pcl726 driver. An invalid interrupt request (IRQ) number, such as 0x80008000, could be passed to the system, leading to an out-of-bounds (oob) error. The issue arises from insufficient validation of the interrupt number provided by the user. The code did not prevent users from passing in an irq number that was too large.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
