Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the efct device init() function within the Linux kernel. Specifically, when efct scsi reg fc transport() fails, the efct scsi tgt driver exit() function is not called, leading to unreleased memory allocated by efct scsi tgt driver init(). This results in a memory leak. The unreferenced object size is 2048. The backtrace includes function calls to kmalloc trace, target register template, and efct scsi tgt driver init.
