Above issue happens as follows:

fc_release_transport(bfad_im_scsi_transport_template);
if (error)
goto ext;
ext:
bfad_im_module_exit();
fc_release_transport(bfad_im_scsi_transport_template);
--> Trigger double release
Don't call bfad_im_module_exit() if bfad_im_module_init() failed.
The Linux kernel CVE team has assigned CVE-2024-53227 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
