CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's ALSA dummy driver, which inadequately validates the card index during device probing, potentially allowing out-of-bounds access if an invalid index is provided through the sysfs interface. This can lead to memory corruption or system instability. Linux system administrators and developers utilizing the ALSA dummy driver should prioritize applying the relevant patches to mitigate potential exploitation risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: dummy: Check card index validity at probe snd_dummy_probe() blindly trusts that the given devptr->id value is within the proper card index range. It's OK for the devices the driver itself creates at the module probe time, but if the device is bound manually via sysfs interface, this could be -1 as "none", and this leads to OOB access for index[] and other parameters. Add a sanity check for the card index and warn/correct it if it's a value out of the range.
