Description

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix null ndlp ptr dereference in abnormal exit path for GFT_ID An error case exit from lpfc_cmpl_ct_cmd_gft_id() results in a call to lpfc_nlp_put() with a null pointer to a nodelist structure. Changed lpfc_cmpl_ct_cmd_gft_id() to initialize nodelist pointer upon entry.

Executive Summary

This vulnerability is a null pointer dereference in the Linux kernel's lpfc driver. Specifically, in an error case within the function lpfc_cmpl_ct_cmd_gft_id(), a call is made to lpfc_nlp_put() with a null pointer to a nodelist structure, which can cause abnormal behavior or crashes. The fix involved initializing the nodelist pointer upon entry to prevent this null dereference.

Impact Analysis

The vulnerability can cause the Linux kernel to dereference a null pointer, potentially leading to system crashes or instability when the lpfc driver encounters certain error conditions. This could affect system availability or reliability.
