NewCVE-2023-53038 (opens in a new tab)How to fix?
Upgrade SLES:15.5 kernel-default-livepatch to version 5.14.21-150500.55.110.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-default-livepatch package and not the kernel-default-livepatch package as distributed by SLES.
See How to fix? for SLES:15.5 relevant fixed versions and status.
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.
