CVE-2026-90020

A flaw was found in the Linux kernel's USB gadget subsystem. A race condition in the gadgetdevioctl function, where a pointer is read before a lock is acquired, can lead to a null pointer dereference. A local attacker could exploit this timing issue during a concurrent bind operation, potentially...
