Last modified

CVE-2023-53038 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
