CVE-2026-80812 affecting package kernel for versions less than 6.6.157.1-1

Type: advisorySource: OSV1 source record

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.
