NULL pointer dereference in Linux kernel - CVE-2024-26623

Vulnerability identifier: #VU90630

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-2024-26623

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 pdsc_setup(), pdsc_stop() and pdsc_fw_down() functions in drivers/net/ethernet/amd/pds_core/core.c, within the pdsc_process_notifyq(), pdsc_process_adminq(), pds_core_intr_credits(), pdsc_adminq_isr(), pdsc_adminq_post() and queue_work() functions in drivers/net/ethernet/amd/pds_core/adminq.c. A local user can perform a denial of service (DoS) attack.
