CVE-2024-50026 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: wd33c93: Don’t use stale scsi_pointer value

A regression was introduced with commit dbb2da557a6a (\scsi: wd33c93: Move the SCSI pointer to private command data) which results in an oops in wd33c93_intr(). That commit added the scsi_pointer variable and initialized it from hostdata->connected. However during selection hostdata->connected is not yet valid. Fix this by getting the current scsi_pointer from hostdata->selecting.
