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.

Can you explain this vulnerability to me?

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.


How can this vulnerability impact me? :

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.
