NULL pointer dereference in Linux kernel - CVE-2023-53038

Vulnerability identifier: #VU108466

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2023-53038

CWE-ID: CWE-476

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the lpfc_read_object() function in drivers/scsi/lpfc/lpfc_sli.c, within the lpfc_sli4_cgn_params_read() function in drivers/scsi/lpfc/lpfc_init.c. A local user can perform a denial of service (DoS) attack.
