CVE-2024-53239

Summary

CVE-2024-53239 is a vulnerability affecting the Linux kernel's ALSA (Advanced Linux Sound Architecture) subsystem, specifically the 6fire driver. The issue arises due to the premature release of resources in the 6fire code. After a call to usb6fire_chip_abort(), the driver attempts to release resources. However, at this moment, the card object might still be in use, leading to potential Use-After-Free (UAF) conditions. To mitigate this risk, the release of resources has been moved to the card's private_free instead of manually calling usb6fire_chip_destroy() at the USB disconnect callback.
