Description
In the Linux kernel, the following vulnerability has been resolved: most: usb: fix double free on late probe failure The MOST subsystem has a non-standard registration function which frees the interface on registration failures and on deregistration. This unsurprisingly leads to bugs in the MOST drivers, and a couple of recent changes turned a reference underflow and use-after-free in the USB driver into several double free and a use-after-free on late probe failures.

Impact Analysis

This vulnerability can lead to memory corruption issues such as double free and use-after-free errors, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges on affected systems.

Executive Summary

This vulnerability is in the Linux kernel's MOST subsystem related to USB drivers. It involves a double free and use-after-free issue caused by the MOST subsystem's non-standard registration function, which frees the interface on registration failures and deregistration. Recent changes caused reference underflow and use-after-free bugs to turn into multiple double free and use-after-free errors during late probe failures.
