Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s comedi subsystem, specifically within the das6402 driver. An unchecked integer value,
it->options[1], received from userspace, can lead to a bit shift operation that is out of bounds. This occurs when checking for supported IRQ numbers. The vulnerable code uses (1 << it->options[1]) & 0x8cec without validating the range of it->options[1]. Valid values for it->options[1] that select the IRQ are expected to be within the range of 1 to 15, with 0 disabling interrupts.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
