Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a memory leak in the
compat insnlist() function, which handles the 32-bit version of the COMEDI INSNLIST ioctl when CONFIG COMPAT is enabled. This function allocates memory to hold an array of struct comedi insn converted from the 32-bit version in user space, but the memory is only freed if there is a fault while filling the array, otherwise it is leaked. The leak has been fixed by adding a call to kfree().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
