Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue concerns the Linux kernel, specifically the scsi: lpfc component. When the HBA is undergoing a reset or handling an errata event, NULL pointer dereference crashes may occur in routines such as
lpfc sli flush io rings(), lpfc dev loss tmo callbk(), or lpfc abort handler(). To address this, NULL pointer checks have been added before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
