CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel's ALSA serial-u16550 driver allows for out-of-bounds (OOB) access due to inadequate validation of the card index during device probing, particularly when devices are manually bound via the sysfs interface. This could potentially lead to memory corruption or system instability. Organizations using affected Linux systems, especially those relying on ALSA for audio or serial communication, should prioritize applying patches to mitigate this risk.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: serial-u16550: Check card index validity at probe serial-u16550 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.
