Vulnerability CVE-2024-43821
Published: 2024-08-17
| Description: |
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix a possible null pointer dereference
In function lpfc_xcvr_data_show, the memory allocation with kmalloc might
fail, thereby making rdp_context a null pointer. In the following context
and functions that use this pointer, there are dereferencing operations,
leading to null pointer dereference.
To fix this issue, a null pointer check should be added. If it is null,
use scnprintf to notify the user and return len. |
