- Summary
- scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths
When the HBA is undergoing a reset or is handling an errata event, NULL ptr dereference crashes may occur in routines such as lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or lpfc_abort_handler().
Add NULL ptr checks before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler.
