FKIE_CVE-2026-80966

Vulnerability from fkie_nvd - Published: 2026-09-11 20:19 - Updated: 2026-09-14 13:18
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: portman2x4: Check card index validity at probe Although portman2x4 driver has a check of the given devptr->id value, it doesn't check for a negative id, which is often given as "none" or such value when bound via sysfs. This may lead 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.
