3) NULL pointer dereference

EUVDB-ID: #VU87369

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-26595

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error within the spectrum_acl_tcam() function in drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_tcam.c. A local user can pass specially crafted data to the driver and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
