Description OSIDB Bzimport 2025-09-04 16:04:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: bfa: Double-free fix

When the bfad_im_probe() function fails during initialization, the memory
pointed to by bfad->im is freed without setting bfad->im to NULL.

Subsequently, during driver uninstallation, when the state machine enters
the bfad_sm_stopping state and calls the bfad_im_probe_undo() function,
it attempts to free the memory pointed to by bfad->im again, thereby
triggering a double-free vulnerability.

Set bfad->im to NULL if probing fails.

For production environments using the bfa driver, is there any recommended interim measure while waiting for the official update?
