CyberRota Analysis
AI-GeneratedThe virmidi driver in the Linux kernel is vulnerable due to a lack of validation for the card index during device probing, which can lead to out-of-bounds access if the device is manually bound via the sysfs interface. This vulnerability could potentially allow an attacker to exploit memory access issues, leading to system instability or unauthorized access. Linux system administrators and developers utilizing the ALSA framework should prioritize addressing this vulnerability to ensure the integrity and security of their systems.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: virmidi: Check card index validity at probe virmidi driver blindly trusts that the given devptr->id value is within the proper card index range at probe. 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.
