Vulnerability identifier: #VU96353

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-2022-48884

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 mlx5_cmd_init(), dma_pool_destroy() and mlx5_cmd_cleanup() functions in drivers/net/ethernet/mellanox/mlx5/core/cmd.c. A local user can perform a denial of service (DoS) attack.
