| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the ALSA 6fire code in the Linux kernel, where resources are released at the wrong time, potentially leading to use-after-free (UAF) errors. The current code tries to release resources right after the call of
usb6fire chip abort(), but the card object might still be in use. To avoid potential UAFs, the release of resources has been moved to the card's private free instead of the manual call of usb6fire chip destroy() at the USB disconnect callback.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
