n 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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: wd33c93: No usar valor scsi_pointer obsoleto Se introdujo una regresión con el commit dbb2da557a6a ("scsi: wd33c93: Mover el puntero SCSI a datos de comando privados") que da como resultado un error en wd33c93_intr(). Esa confirmación agregó la variable scsi_pointer y la inicializó desde hostdata->connected. Sin embargo, durante la selección, hostdata->connected aún no es válido. Solucione esto obteniendo el scsi_pointer actual desde hostdata->selecting.
