Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains use-after-free flaws within the fbdev and smscufx components. These flaws can occur when a USB device is physically removed. The fix introduces the
ufx ops destroy() function to the fb destroy method of fb ops, which includes a kref put() call that ultimately invokes ufx free(). This change aims to prevent multiple use-after-free conditions.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
