Daily digests

A race condition in the Linux kernel's USB gadget HID function driver lets a local attacker trigger use-after-free memory corruption. Because the list and spinlock weren't initialized early enough, an attacker with local access could escalate privileges or crash the system. Exploitation requires local access to a system using USB gadget mode, which limits the blast radius.
