CVE-2023-53038

  2. Vulnerabilities (CVE)
  3. CVE-2023-53038
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Check kzalloc() in lpfc_sli4_cgn_params_read() If kzalloc() fails in lpfc_sli4_cgn_params_read(), then we rely on lpfc_read_object()'s routine to NULL check pdata. Currently, an early return error is thrown from lpfc_read_object() to protect us from NULL ptr dereference, but the errno code is -ENODEV. Change the errno code to a more appropriate -ENOMEM.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Comprobación de kzalloc() en lpfc_sli4_cgn_params_read(). Si kzalloc() falla en lpfc_sli4_cgn_params_read(), dependemos de la rutina de lpfc_read_object() para comprobar si pdata es nulo. Actualmente, lpfc_read_object() genera un error de retorno anticipado para protegernos de la desreferencia de ptr nulo, pero el código de error es -ENODEV. Cambie el código de error a -ENOMEM, que es más apropiado.
