CVE-2025-39676
In the Linux kernel, the following vulnerability has been resolved: scsi: qla4xxx: Prevent a potential error pointer dereference The qla4xxx_get_ep_fwdb() function is supposed to return NULL on error, but qla4xxx_ep_connect() returns error pointers.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
