  2. Vulnerabilities (CVE)
  3. CVE-2021-47565
In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix kernel panic during drive powercycle test While looping over shost's sdev list it is possible that one of the drives is getting removed and its sas_target object is freed but its sdev object remains intact. Consequently, a kernel panic can occur while the driver is trying to access the sas_address field of sas_target object without also checking the sas_target object for NULL.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: mpt3sas: solucionó el pánico del kernel durante la prueba de ciclo de energía de la unidad. Mientras se recorre la lista sdev de shost, es posible que una de las unidades se esté eliminando y su objeto sas_target se libere pero su objeto sdev permanece intacta. En consecuencia, puede ocurrir un pánico en el kernel mientras el controlador intenta acceder al campo sas_address del objeto sas_target sin verificar también si el objeto sas_target es NULL.
