CVE-2026-72482

A flaw was found in the gpib component of the Linux kernel. A double decrement of a descriptor counter within the commandioctl function can lead to a counter underflow. This re-enables a use-after-free vulnerability, where a concurrently active descriptor can be prematurely freed. This could resu...
